This is a great duty gun. Made strictly for battle ready use. There are no external buttons that snag. When you need the gun it shoots, and is easy to maintain. Great weapon.

i have had a glock since 1992 and have never had a malfunction. i do not like a safety on a duty weapon. i did not like the stock sights(night sites are best). it is a true duty weapon.

I have carried other duty weapons in the past. However the Glock 21 is a good duty weapon of choice.

hi cap ,hi cabiler , light, nice trigger.

I have carried this weapon for the last 12 years and I have never had a problem with it . Though the recoil is harsh.

The weapon fits my hand and works with my grip. I have very large hands and the glock 21 works. Very user friendly easy to field strip for cleaning. Works very well in wet environments.

Smooth to fire, easy to use, easy to clean and never fouls up. PAcks a big punch and holds alot of lead.

As an instructor I have put 5000 to 10000 rounds through my agency Glock 21 and the only malfuntions I have had I had to set up for drills. A solid and dependable gun.

This is a true officer's weapon with enough stopping power and versatility to "go the distance" in any confrontation.

I have been an officer for 13 years now and have carried Glocks for most of that time. I currently carry the G21SF as it replaced my G23. I started my career carring a 45, but the G21 was always a hair to big for my hands. The new G21SF is a great duty weapon. I have over 5000 rounds thorough it now and not a single malfunction. The 45 ACP is making a comeback in LE, and I believe this a great piece to take a look at if your considering the switch to 45.

Overall a good pistol.

My dept carries the 22 model but I have a 21 model at home and I so wish I could use it at work. It is so nice to shoot. Very powerfull and reliable.

Point and shoot. Sweet!

While shooting this weapon I had a catastrophic failure (kaboom). The weapon was sheared into two pieces and I had brass and plastic embedded in my face.
My agency had another kaboom three days later with the Glock 21. This officer was injured, and cant work because of the pain.
It should be noted that my weapon was cleaned with authorized materials the night before going to the range. I was shooting factory practice ammo.
Officers in my agency no longer carry the .45 Glocks, sadly we are forced to carry the 9mm.
I shudder to think what would have happened if I was on the street and my weapon exploded in my face.
I would carry the .45 again if Glock was able to fix the problem.

5 stars.glock is the best gun for cop duty no matter what the caliber, well except the 9mm.

In the SF version this is probably the most innovative handgun to hit the market this year. I've shot a couple of the SF's. Typical Glock 45 accuracy, very good.

The Glock 21 is an excellent combat firearm. I was an avid Sig Sauer fan until I took the Glock out for a "test ride". I was in a firefight with a Sig 226 (9mm) but now carry the Glock 21 (.45 caliber) as my duty weapon. I carry the Glock 30 as a back-up and off-duty. Hitting center mass is fun and the Glocks are easy to disassemble and clean.

I've owned a Glock 21 for several years and I know it will get the job done. It's durable, accurate, and reliable.

Excellent!!!! I've carried this on the street for 8.5 yrs. Never a malfunction or misfire.. and I've put thousnads of rounds through it

great firearm need I say more....

The glock 21 speaks for itself.

Love Glock! Can't go wrong with any caliber!

I have carried both S&W autos and revolvers. But after shooting the glock to me there is not a better gun on the market.

I used this gun when I was a deputy. I hated it. It was like holding a 2x4.

Low maintenance, hi durability. This is a great gun!

Out of large frame .45 's the Glock 21 is excellent. This weapon is very durable and most of all very accurate!!

I carried one of these several years ago and it was one of the best .45 pistols I have ever shot. It fit my hand well, was back on target quickly and felt minimal recoil. With 3 mags I had 40 rounds ready to go and with that much .45 if you ran out of ammo, you were not supposed to still be there.

My only complaint about this weapon is that, being female, I find that the grips are too wide for my hand. This is a department issue gun and so I have no choice in what to carry. I am not comfortable with it due to this fact.

I have a department issued .45. I love my gun, I could be one of the exceptions to the rule. Being a firearms instructor, I often hear females complain that it is to big. I don't have big hands and I do just fine with it. I've never had a problem with mine.

The Glock 21 is a reliable hand gun, but the grip is a little thick and unconfortable for those with small hand. I like the feel of the New Glock 21SF with the thinner grips. My only other complaint is recoil that is caused by light plastic guns.

Great to shoot. I have never had a malfunction with it. EASY to clean.

Im not one who is real big with weapons. I honestly am scared of guns.. But If its easy to clean and have never had a malfunction then its one for me!!

my carry weapon. love it. its light, very dependable.

That is the gun I used on duty. Great punch. Quite reliable on the shooting range.

Good firearm. Its always reliable. Shoots great and easy to handle.

Makes a nice, big hole in whatever you hit with the round. What else needs to be said??

I carried the Mod 21 for about 5 years on duty. I was carrying a Smith 5609 till one day I went to the range to qualify and could not hit the side of a barn which was very unusual for me. Went the next day to the eye doctor and got glasses thinking that was the problem but the next time on the range, I had the same thing happen. A friend was on the range that day and offered to let me shoot his Mod 21 and I put three rounds in a hole the size of a dime from 30 yards and went the next day and ordered myself a Glock Mod 21. The Lt. over the range said that the sights on my 5906 were out of whack and had to be sent back to Smith & Wesson to be corrected.
I never had any problems qualifying after getting my Glock.

I carry a Glock 21 and I would not carry any other make of gun. Glock in my opionion are very reliable and I do not worry that I will have to use it and it will not work.

The Glock 21 is an awesome weapon. I have carried it for approximately five years. It is an easy weapon to clean and maintain. When I chose a firearm to use on duty it MUST be a weapon I trust. My Glock 21 is a dependable firearm that has never misfired or jammed. I would recommend Glock to anyone.

I have carried this weapon for 6.5 years and love it!! With 13 rounds in the magazine and the stopping power of .45ACP, you can't go wrong. After 1000's of rounds, I have never had a malfunction.

This is the standard issue handgun for my department. Large frame for smaller shooter, the new S.F. should take care of the size. I have over 20,000 rounds through mine and it is working as well as ever. I recommend this handgun to anyone working in "Hostile" environments. Though I am still a 1911 fan, this handgun is my first choice when it comes to a working handgun.

I love this gun. Fits well in my small hands. Very smooth shooting, easy to handle, light and not much recoil. I shoot 98 or above with all my Glocks. Love them!

This is my duty weapon when on patrol. I love the .45 ACP, and this is a fine weapon. Easy to clean, accurate, and always ready for battle. I use a Hogue rubber grip for the Glock 21, and feel very comfortable handling this weapon.

Great service handgun. Most of the of the officers in my department carry it and we have no complaints. I have never had a problem with it.

Excellent weapon, I have carried this and a H&K. H&K is also a fine weapon but for the money you cant go wrong with this weapon.

I love my Glock. I used as my duty weapon, but I also carry it with me sometimes. It is a great gun and shoots with great accuracy. Love it!

a very dependable weapon i love this gun

I am currently carrying a Glock 22, however I have been more than impressed with the Glock 21 .45 cal. Packs a punch and with, in my opinion, less felt recoil

I have carried this weapon for over 6 years and never a problem and also maintains easily, not to mention can out shoot all others on the dept. even the 5.7's [ we shoot what we can buy]

Awesome firearm. I trust my life with this gun!!

This is the gun that works in the mud, rain, sand, dirt, snow or anything else mother nature throws at it, AND STILL FIRES

one of the most dependable guns ever made

Functions flawessly in adverse conditions, does not have to be babied, every trigger is the same.. Best out of the box shooting I have experienced. There are pistols and there are combat weapons. I prefer the Glock combat weapon.

This is the reason they call it "Glock Perfection." This is the perfect weapon. Supreme stopping power.

The Glock 21 is what our department issues to all officers. I have had other handguns in the past but none compare to this one.

My only complaint in the grip size. I have stubby hands so its a little hard to handle.

A Glock is a Glock is a Glock ..... though a good duty gun I'm not much of a fan. Due to it's larger frame I find it very uncomfortable to shoot despite being able to qualify with it every year. I love the .45cal but in my opinion nothing can beat the combat record of a good Model 1911. Damn I love those guns.

Eight years on the force and eight years with the Glock 21. I,ve shot pleanty of hand guns, semi auto, revolvers. My choice of duty weapon is the Glock 21.

very dependable and easy to clean

Easy to use, reliable, makes big holes. Enough said.

Great blunt force trauma when needed

This is my off duty weapon. I trust no other. GREAT GUN

Very good weapon. This is standard issue by my department.

Great weapon as is any glock. Powerful. It's the department issue gun. It fits my hands perfectly I love the feel of the gun. If your a bigger guy and you shoot this guy, you will love the feeling compared to some tiny gripped 9mm or .40. This the big man sized gun. Maybe be too large for some people with smaller hands, I have heard some of the smaller guys in the department complain about how big the gun is.

I love this handgun. I have owned a 21 for 6 years and it has never given me a problem. All you have to do is maintain it and it will never fail you. It fits perfectly in my hand, the trigger pull is the same everytime and it's consistant. I would highly recommend this handgun to anybody!!

I hesitated giving up my 1911 copy due to the make not being supported by my local department. However, after 3,500+ rounds and NO Failures except those induced by instructors I have nothing but good to say. This is the only pistol I will own and trust. Everytime I have pulled the trigger it has gone BANG! Nothing more to say!

Proud NEW owner of Glock 21. I have never owned a Glock until recently. This is my new duty weapon and I love it. It is extremely accurate and the recoil is not much more than a Glock 22. Fits my hand perfect.

I used to be a 1911 guy untill I experienced the reliabilty of this sidearm! I love having 13+1 rounds of 45 without a magazine change. This weapon is not for guys with small hands!

nice gun. very reliable. low maintenance. wont think twice in carrying this gun to work.

I carry this as a off-duty weapon. I love Glock's. They are absolutely one of the most reliable weapons on the market. The only thing it doesn't do well, is fire frangible ammo. Don't know why.

Accurate, tough and reliable... I carry this as a backup weapon in my car and have more faith in it than my primary duty weapon, the Sig Sauer P226R. In an ideal situation, this is the tool that I would grab to get the job done in a firefight. The Sig would simply watch from the sideline...

A lot bigger than my 17, but it gets the job done. Kind of big for females, it takes some getting used to. When there is a round in the chamer and your loading a full magazine you really have to jam it in there to seat. I like the load indicator to let you know if there is a round in the chamber, no more press checks.

my fav. one.

Very durable weapon. I like it.

I carried a S7W 686 357 for years the a S& W Sigma 357. The glock 21 is by far the best duty weapon I have ever carried. I love the full size grip as I have a large hand, and the stopping power of the .45 cal is awesome.!

I carry this weapon on duty and I have never had it jam. In out department we qualify 2 times a year and I have never even had a miss fire. I truly love my weapon.

Great Product!!!!

my duty weapon of choice! excellent waepon, great accuracy. i would carry nothing else!

Great Weapon!

NICE

My only complaint is the grip size is too large. It shoot it fine and it was reliable, until I tried to shoot with gloves on. Between the size fo the grip and the length of the pull I have a hard time when I added a glove to the reciepe. I think the 21SF will be a better choice for most people.

The Glock 21 far surpasses any other weapon I own, in terms of reliability, ruggedness, ease of use, low maintenance and expense. I have long considered most 1911 style pistols to be superior in terms of accuracy, where as the Glock 21 is the work horse of the .45 caliber weapons. Most 1911's require a fair amount of maintenance and the Glock can be used, abused time and again.

Add an internal laser from lasermax.com and you can't go wrong.

Great weapon and easy to shoot (once you get use to it).

Great weapon it was issued at my last 2 agencies.

I have this model in 45 cal, I use it for a backup and for home.

I never fired a Glock, until I got this job. I had fired tens of thousand of round through the 9mm Baretta. My first duty pistol was a Glock 22, I was suprised at how durable it was, never a malfunction, not too happy with the accuracy, but I hadn't shot competively in almost 10 years. My department switched to the Glock 21 same duarability but the accuracy has improved drastically.

#1 pick

Like the feel, weight and grip. Grip size is important, i am 6'4" and have large hands and this is the FIRST weapon that i have truely felt comfortable handling. I am particularly taken by the recoil. It has a firm kick but if your used to shooting, you can handle it with ease. Never had a jam and theres not alot of "extra" switches to hang up on gear or clothing. A definit recommended piece to carry for the larger haned officer.

I have owned several different service weapons over the past 15 years. The GLock 21 has been by far my favorite. I have the Glock laser/light combo mounted on it. I carry it in a 6280, perfect match.

Great on duty weapon, good stopping power.

I have carried this weapon as a duty sidearm for sometime, it's very reliable and easily maintained. Not to mention a very capable round .45 ACP!!!

good sidearm weapon

Best handgun that I have used so far

It's pretty good. It is fairly accurate and easy to use. My only complaint is that it is rather large.

Phenomenal pistol!! Shoots great, and the wife loves it too!

Can't go wrong w/ GLOCK..

very nice firearm. I carry one

This is an great duty weapon to have

We went to the 21 and 22 (for the little guys), and we haven't had too many problems with it. They shoot very well right out of the box, when they get dirty, and are extremely easy to clean.

good product handles great in all types of weather

Awesome .45.. First .45 i've owned...Reliable just like all other Glocks.

This is the best gun that I have ever owned

Bad to the Bone!!! Glock is in my opinion the toughest, most accurate handgun made. And chambered in the 45 caliber, watch out bad guy

As a firearms instructor, I get to shoot a lot of different weapons. I personally carry the Glock 21 for several reasons. First, it is .45 ACP. Second it carries 13+1 of .45 ACP. Third, it shoots whatever ammo I stuff into the mag, period. Never had a malfunction. Fourth, it is accurate. Finally, I have big hands and the issue Glock 22 feels like a toy. There are other pistols as good as Glock, but none that are appreciably better. I would take either the Glock 21 or a good 1911 any day, but I know the Glock 21 will work 100% right out of the box, whereas many 1911's must be broken in or adjusted before I'll bet my life on them.

how can i put this ????? LOVE IT

Very reliable and easy maintenance. Bulky for concealment but can be customized.

Very reliable and almost idiot proof......the 21SF (slim frame) might be a better choice to fit hands of all sizes.

i bought a new glock 21 while i was home on leave from Iraq i have always loved the 45 out of the box with factory sights i was putting the rounds where i wanted them i like the way that the pistol fits in my hands I i have to say i like this pistol more than i liked my 1911

It is a powerful versatile weapon. I carry the SF and wouldn't carry anything else.

I work at a department where we provide everything. I owned my 21sf before starting and naturally choose it over everything else I own to be my duty weapon. At quals I out shot everyone, even two with 1911s. Never a malfuction, 13+1 of capacity, extremely accurate for a duty weapon, just what more can a person ask for? This will always be on my hip!

has been my service weapon and personal for 16 yrs as a ofcr. never had a problem with it, easy to clean and maintain. never fail to qualify at the range. i have the first generation glock-21 (before the rail attachment were added) and its still going strong.

Proven, tested, and in my experience, NEVER will it let you down.

Greatest handgun I have owned

I pack the 21 as my duty weapon. Have fired several thousands of rounds through it with out problems. Always feel confident that when I pull the trigger it will go off. Won't pack anything else.

Great weapon , and it is standard issue for my department. Most of the detectives carry the compact version which is the Glock 30 but I like the full size so I stuck with it after making detective. Its a bit large for small hands though. The new 21sf (short frame) is better for small hands.

I have one Love it. Keep it clean and has never once had a problem in the 6 years i have onwned it

Works for me.

Just bought one of these babies and I LOVE it. It's lightweight enough for my bride to handle, simple and easy to use. I used to like the 9mm Beretta quite a bit (despite the bad press about it), but now found a new love . . .

Great Duty Weapon! Nothing beats a 45.

.45 is power I like having. It is our new duty weapon, we are currently making the transition and I couldn't be happier. Going from the model 22 .40 cal to this is nothing more than re-qualifying and I love it. The grip is a bit more like a bar of soap, sure, but the platform is simplicity itself, just point and click. I do like the higher number of rounds with the .40 but I can get over that. The recoil is lighter since the muzzle velocity is lower and that makes it even easier to get multiple rounds on target in less time.

No problems, works everytime! Incredible stopping power!!! (replaced my S&W 4006TSW)

Great firearm the first time I fired a 21 was this year at basic law enforcement training. I like it better that my glock 22. A well crafted firearm.

A great gun that does exactly what is asked of it! At the agency where I started my career I carried a Smith and Wesson Sigma 40 cal and had nothing but problems with it. Numerous malfunctions occured (including having to push the pin back into the frame of the gun with a finger in the middle of qualification rounds) and I was always shooting low/left because of the heavy trigger pull. I had difficulty qualifying right before I left, but within a few days of starting at my current agency I had to qualify with my newly issued 21. I had never fired the gun before, but I qualified on my first round and have never had a problem since!

45 acp is the way to go. I carry this weapon on duty and i love it.

I carry this weapon on duty and off (off duty because I haven't gotten the baby version yet) it's great, I've got .45+P ammo and this gun packs a punch you won't be gettin up from. Easy to maintain, extremely reliable, great all around gun!

Very reliable and effective stopping power, plus accuracy.

This is my primary duty firearm. Extremely accurate, never had a malfunction, and you can't beat 45 stopping power. The only bad thing I can think of regarding this firearm is that it may be to large for individuals with smaller hands.

I am a firearms instructor for the state of Oklahoma and I am currently using a Glock 21C. I have had no problems with this gun and it shoots extremely well. I have won a few competitions with it.

I current own many Glocks and like them all.

This is the main weapon used by all of the agencys in our county with the exception of 2 and one of those is the State Police. This weapon is very dependible, accurate, and durable. It is nice to be able to carry a lot of stopping power in a .45 and have the high capacity to go with it. I wouldn't trade this for anything.

Carried this weapon the last ten years of my career. I switched to the Sig P226 and feel more comfortable with the Sig. I still feel this is a good weapon

little to no kick back

I have this gun, and i would never get rid of it for anything.

First uniformed duty weapon I carried. By far my favorite gun I have ever and still own. You just can't go wrong with a Glock in .45ACP

This is a great gun I now carry it off duty. Glock makes very dependable weapons, they are also fun to shoot.

Hand grips a little chunky, but shoots great.

Like this gun a lot. Its big so its gonna be a service pistol unless your big enough to conceal it. Shoots great and has mild recoil.

My dad carries this baby on duty, and let me tell you! exellence is in its name! best performing gun i've shot. Perfect handling, nice sights, big ass caliber (.45). Works well after being thrown in mud, water, concrete, dirt, sand, etc. great product!

I have carried one on duty since 2000 and have had no problems with it. I enjoy range pratice and qualification with it as there is almost no recoil as with other .45s. It makes it easier to come back on target after multiple rounds, and it is easy to clean and keep clean. A perfect grip on the weapon with my long fingers. Just a wonderful weapon to shoot. From 1995 till 2000 I carried a Smith + Wesson 357 Magnum that I had when I started my police career in 1976. I had to retire that one and went right to the Glock 21 as I felt it was and still is comparable to the 357.

Carried this gun twelve years.....not a single problem!!

I Have a Glock 21 sf (45 ACP) that is absolutly Awesome,very dependable, very light weight,high capacity mag (13), awesome knockdown power, easy to breakdown,very concealable,bottom line it alway's at my side A++++

Easy recoil, quick target aquisition after firing, never had a jam or misfed. Easy to maintain.

I have been using this type of firearm for years and in my opinion it is the best on the market. Have shot on the range for almost 9 years and never has jammed and no problems. Very easy to take of.

I have been carrying a glock 21 for 7 years now. I like how it shoots. I have changed out the grips.

My gun of choice!

Love my Glocks.

I love this gun! I can't carry it as my duty sidearm, as we are required to carry .40 cal, but, in my opinion, it is a better gun than my Glock 22.

Great firearm. We issued them to our entire department for duty use. Great feel. Point and shoot.

I have owned the 21 Glock for several years and consider it to be one of the greatest firearms of the century. The weapon is damn near perfect. Everything from the grip, to the adjustable Glock night sights are right on. I have fired this weapon with the standard fixed sights with very good results, but prefer the upgraded sights. Trigger pull is exceptional, with a strong but easy pull. I usually shoot a 280grn Jacketed Hollowpoint round and have acheived very tight groups to 15 yards. 25 yards prone shooting resulted in better shots than I have ever fired with another weapon under the same conditions.

I have carried my current Glock 21 for ten years and fired tens of thousands of rounds through it without a single break down of the gun. I know that when I need this weapon to do its job it will not fail me.

This is the only Glock handgun that I am not a fan of although it still bears Glock's hallmark of high quality. For those with smaller to medium size hand (like myself) this particular piece feels like trying to shoot a .45 with a 2x4 for a grip. I even know of some folks with monster mitts whose hands do not adequately fit this firearm.

After I first bought this gun I took it out and tested it. I set up a soda can and walked about 20 yards away and turned around, aimed and fired. I was very impressed that I hit the can dead center, right at the point I had aimed for. Not only is it accurate but it fits my hand perfectly. I also enjoy knowing that I have that kind of stopping power. When I hit that can I sent it about 15 feet back into a bush and realised it wasn't exactly the best target to be shooting at. But non the less, I hit a rather small target with impressive accuracy and at the time I knew I had a gun that would be with me for a long time. I had not ever fired a glock before that. I had this gun for about two months before I ever took it out to see what it could do and in an instant it rose far above any expectation I thought I would ever have for a 45.

I wasn't sure about going from the .40 to the .45 because a have relatively small hands. After putting a few rounds down range, I was convinced. This is a great gun and it is very easy to shoot.

Having carried the 9mm and the .40, I had never fired a .45 before. After firing this weapon I was in heaven and will not go back down to the 9mm or the .40. THis is the best weapon I have been issued.

Awsome weapon. I have had mine since 1996 and would not trade it for anything. Dependable and has brought me home safe twice.

The only problem with this side arm is trying to find it. Glock is the ultimate firearm...

This weapon fires smooth and true. My weapon was actually under water and I have had no problems with it.

Easy to use and easy to learn to fire!

The Glock 21 is a great weapon, I have never had any trouble with it, the only thing I do not like is our trijicon night sites.

Been using this gun for a short time now but it is extremely accurate and has a solid recoil that lets you get back on target very quickly. I was able to hit a target that was 346 yards away yesterday on my 4th shot if that isnt saying something then i dont know what is.

i have the sf little bit handle love it

Its a Glock

I carry mine with confidence every day and every where I go. I own 2 of them. As a Glock armorer I highly recommend it for duty.

The weight of this gun is very light. The sights that comefrom factory are awsome and its a very accurate shooting gun.

Overall a very solid and dependable firearm. But unless you have the hands, you're better off with the 21 SF. I've heard the comment, that holding a standard 21, is like holding a bar of soap. Fact is, if it doesn't fit flush in your hand, then it's not for you. This couldn't be more accurate, as the 21 does pack a considerable amount of recoil and if you're not comfortable holding it, then chances are, you'll have less sucess controlling it. But overall, there's a reason so many LE agencies carry this model and brand. I own this particular piece for range firing and primarily home defense. Definitely would not reccommend for CC, unless it's the SF.
If you're considering this piece for primary home defense, a word of advice... DO NOT waste your money on the Night Sights. I've seen a lot of people buy this accessory and end up wondering why they did in the first place. Instead, spend a fraction of the price that you would have spent on night sights and get yourself a GTL-10 or 11. I highly reccommend this as a must-have, for home defense. If in the unfortunate situation an armed assailant does enter your home, you want to be able to see THEM first, instead of being a glow-in-the-dark bullseye looking for shadows. Not only that but you always want to be aware of, at "whom" and "where" you're shooting. Chances are an assailant's eyes have already adjusted to the darkness, so he will be able to see better than John "Homeowner", who just rolled out of bed. And let's face it... I seriously doubt they're going to turn the lights on for you.

The power of .45 A.C.P. in a GLOCK need not say more. The frame is a little thick for smaller hands so I recommend the GLOCK 21SF, with a bit smaller circumfirence in the grip.

I love it!

i have the SF version of this gun I am used to carrying a .40 so this is like the same just with alot more stopping power

Excellent choice for reliability. I carried this for 4 years, never a malfunction, aside from drills. It's great for people with larger hands. Someone with shorter fingers might struggle a bit to keep a good fighting grip. Other than that I would highly recommend this as a duty weapon.

This has been the best gun I've carried...Carried for little 14yrs. and have never had a problem with it at all. Capacity, function (simple), durability....

This is my weapon of choice for duty carry. It is a good .45, easy to operate but if you have small hands, I wouldn't suggest it. Carries 13+1 and I have had to use it and have not had a malfunction with duty ammo.

Love this weapon, My department carries the Sig 229, .357 sig. Its nice but I have always liked a Glock since I carried one in the Sheriff's Dept.

It doesn't get any better than this.

I worked with a department that carried Smith & Wesson auto's and they were good for nothing more than boat anchors. The Glock is by far the best auto I've ever shot. No safety to forget, just pull and shoot, no question.

Our agency will be switching to the Glock 21SF this month. Our SWAT Team and some of the firearms instructor already have them. It's my opinion that this weapon shoots better than the Model 22 that we've carried for years. When gripping the weapon while holstered, I get the grip that I want each and every time.

good size, good field, accurate,

very smooth and accurate, has a kickof a 9mm

fairly good acuracy at 18 yrds
and little recoil

G21SF, with Trijicon night sights ... most reliable COMBAT weapopn available for law enforcement. Been doing either military duty or active LEO for past 36 years, wished I'd have had this weapon sooner in life.

I bought this weapon, before I entered law enforcement. owned this weapon for 4 years and never had a jam or failure to fire. in my mind this is the best COP weapon out there and I wont be caught carrying anything else on duty.

LOVE THIS GUN. FITS GREAT IN THE HAND FOR A LARGE CAL. HANDGUN. LOW RECOIL AND IS BALANCED WELL.

I love it. Great feel. Even my wife likes it

One of the best!

THE 21 IN 45 CAL. AWSOME STOPPING POWER AND VERY ACCURATE. MY CHOICE AND CCSO.

Great pistol. I have had it since 1992.

I love this weapon.

Accurate, always ready, easy to maintain. Less recoil than a .38 cal. While working nights, I really appreciate the high vis nightsights.

Another classic! I'm speechless!!!

It's lite and accurate. It is the best I have ever shot. It's a gun with a lot of punch.

Most durable and best feeling in my hand of any sidearm I haveI

I love it! Big & powerful, but hard to conceal. I got mine compensated for even less kick. I've had one malfunction in the 2 years I have owned it, not bad at all.

I carry the 21 on duty and love it. The grip is a bit big but once you get used to it you'll never want to put it down!

Great gun

Just loving it babe and way cool

I like the durability and low maintenance.

GREAT GUN

I have the 21Sf love this pistol I have tricked it out with threaded barrel and tac light with XS Big Dot sights. really shoots well!

love it!

Glock 21 is a SUPREME FIRING handgun! I love mine!

Excellent firearm. Glad that the department made the switch a few years ago. Had the Sigma 40 and it was a piece of junk!

Best on the block

shoots great and never fails

Perfect when you absolutely need to stop something dead in its tracks and send a big piece of lead down range. Low recoil, quick double tap. Consistent, reliable, serviceable Duty weapon.

I love to put this big bullet down range! Glock does it right this is a well balanced weapon of choice for a exposed carry duty weapon.

I had used the 22 for 5 years prior to this gun. I did not know what to expect, having only fired 1 other .45 (Colt 1911). Who knew that a larger cal. gun seemingly would have less kick, or at least a different kick. To me, this seems to move more back as opposed to the pop I felt with the 22. Love it and glad to carry it.

This is a great duty gun. It will shoot after just about anything you do to it.. And is easy to maintain.Excellent weapon!!!!

Like they say. Glock perfection! .45 Caliber, large capacity. Good crisp trigger that is the same every time. Accurate as hell and reliable no matter what. Surprisingly the recoil isn't too bad for it being as light as it is. Low maintenance. Cheap. I have small hands and no problems with the standard grip.

The only con is that the grip can be a little slippery when wet.

Very light and very easy recoil ! I LOVE this gun

Very nice weapon with little recoil.

This is my Duty weapon and I would not trade it for anything else.

Absolutely love this gun. I read some of the other reviews about the grip being too thick for them. The Gen 3 model is a little slimmer and the Gen 4 has an interchangable backstrap that allows grip sizing a little better. My Glock 21 never leaves my side. It is the most reliable gun I have ever shot and I have definitely put it through it's paces.

Excellent weapon.

Great weapon to have!!

I read about a local department in oregon having 2 of these caliber glocks blow up on them. I own a Gen 1 Glock 21, 600 rounds put through it, never an issue. Maybe it was a newer Gen that had the issues? Anyways, fantastic gun!

Great weapon thousands of rounds put through mine and have never had a malfunction.

Our Sheriff's Office were just issued the Glock 21. What an outstanding firearm. Hardly any recoil. Stays on target after first round.

Best hand weapon on the market. Tested and proven. Powerful. Check youtube.com under glock. I have 21 SF. Great fit in my hand.

Very practical and easy to use firearm. Loved mine from day one!

The AK-47 of pistols. Its simple and dependable and great fun to shoot.

This is THE patrol pistol of all time. For all the reasons already listed. I was issued mine about 5 years ago and will never go back to anything else. Even added a tac-light to it. With Gold-dots, this is as formidable a sidearm as it gets.

over a thousand rounds,, no hickups,,and nice and light while holding waiting for backup.

Glock has always been a great chose for me. It has the light weight features, but still has the knock down power.

The Best Fu*king hand gun in the world i have own one for a few years be for i was hired when my department first issused the out i jumped on them if there one sidearm I would put my life on its this one

Great sidearm, and easy break down and cleaning

It looks nice.

Great reliable weapon with the needed stopping power. Seems a little big for concealed carry, but you will be amazed that it's still hard to see when concealed. For big hands only!

Outstanding gun! Not for all shooters. Smaller hands might find it difficult to shoot, but the .40 cal is better for that and not much compermise for stopping power. I had my 45 for 15 years before it was authorized it to carry.

I have this one in the compensated and non-compensated models. Love both. Reliably feeds, shoots acurate and after swapping for 3.5 pound triggers and polishing all of the moving edges, they are a pleasure to shoot. I never have had to concern myslef with the reliability issue with these. As long as you have a medium to large hand this one is for you. If not then get the slim frame version. I use them with230 Grain Federal Tactical HST +P rounds and I would not trade them for a 1911 or a Springfield XD. Shot all 3 and do not like them as much as my Glocks

This is one of the best shooting pistols I have shot.

One of the best shooting guns on the planet.

Good size and very dependable.

This is a excellent handgun. Very dependable and packs a punch.

this is my on duty hand gun, it is a nice hand gun I think its a bit big though

Easy to clean and service, comfortable to handle. I love this gun.

Glock is known for it's reliability and dependibility. the product has been tested under the most extreme condition and is worth it's weigh in gold

WENT FROM A MODEL 22, TO MY 21.............. I'M IMPRESSED

JUST AN ALL AROUND GREAT GUN

Sweet weapon. Shoots great with awesome knockdown power.
