My first ever owned Glock, I have had Glock duty weapons (9mm and .45), and have had Colt 1911 duty guns, s&w duty guns, wheel guns of 357 and more...but this Glock is the "right out of the box" best gun I ever shot! I will be carrying this 21SF until I retire next month after 30 years, My Smith & Wesson 9mm saved my life several years ago when I was shot twice in a shootout, and thank God the bad guys only had 6 shooters! Love this gun....now I understand the "Glock fanatics!" ...

If it is a Glock, it is a great gun... The ambidextrous mag catch is a good improvement as well. Glock Fan!

I would have to pick the Glock 21 as my duty weapon becase of its high capacity of .45 cal rounds and the durability of the weapon.

I bought this gun the first day it came out to the market, the only pronlem I had ws finding a consealed holster, it fits great shoots great, best .45 i have ever bought. I will buy nothing but Glock, from here on out

Love it Glock did it right this time never cared for the reg 21 grip was to big even with my big hands. This is my first 45. cal was worried about recoil but this gun has less felt recoil than my 40 cal sig 2340 its a very flat recoil making target recovery very quick trigger feels great easy to double tap. Accurate 100% with trijon nite sites first time out. Holsters were hard to find till we discovered that a reg 21 will fit great I use a G&G Triple retention secures great and easy to draw off duty use a blackhawk serpa paddle back again its for the reg 21 This is truely GLOCK PERFECTION

I've been wanting one for the past couple of weeks after I heard about it. I have the glock 22 and I want the .45

with the smaller grip this gun is managable for people with smaller hands.

The reduced backstrap make the Glock 21SF a better fit than the old 21. The 45 is still the superior combat munition in a pistol. Stay Safe all, and remember.......Front Site Presssssssssssssssssssssssssss.

Love it!

I love this gun!! By far the best Glock I have ever carried!!

I have relatively small hands and this thing fits great! and the fact that its a .45 just rocks!

It's a Glock, what else is there to say!!!!

I carried a SW99 .40 cal for the first nine years with my agency. Recently bought a Glock 22 after I was told only our tactical team would be allowed to carry .45s. Two months later the sheriff changed his mind. I didn't hesitate for a moment and sold my G22 to get the G21SF. My brother carries a regular 21 on duty but it feels way to big in my medium/large hands. The 21SF fits my hands perfectly, feels more like the G22. Very glad I can carry a .45!!!

This is my duty gun and cold weather carry gun. I love it. with a decent set of night sights and a good holster I am comfortable all day and confident that should the need arise the gun will be the least of my problems.
Gotta love the fantastic plastic!

Its a Glock

Its better than a standard Glock 21. It feels like you are shooting a gun and not an angry 2x4. Of course not being able to use older Glock 21 mags due to the ambi mag release is a serious drawback. Also, despite the improvements, it is still a fairly bulky, awkward and uncomfortable firearm to shoot. It is still a Glock so you get all that comes along with that, but for my money, I'll make my .45acp a Sig 220.

Great improvement! I am buying one today. I have hear several good reviews about it. I'm just not sure about the full pictinny rail. Does it effect the holster size?

AWESOME

Great Gun. Easy to shoot, Clean, and with the new modified grip easier to carry for smaller hands. What can I say its a GLOCK

Not a big fan of polymer .45s, too much recoil.

I graduated the academy i 1992. We were just transitioning to .9mm from .38. We went with Glock .9mm. Then we went to .40 cal. We have since worked a deal with Glock that we sent them our Glock pistols and they replaced them with new ones. It was that, or rebuild ours.
Our SWAT team is issued .45. Finally after much begging and cajoling, the G21/G21SF were approved for optional carry. Meaning, if you wanted to carry it, you had to buy it.

I did. I purchased a G21SF and have never once regretted it. I love this pistol. It cycles completely differently than my old .40.

I usually qualify with scores of 91/92/93 percent. I bought the 21SF and the department mandated a swtich from the 5lb trigger to an 8lb trigger. Once they completed the changever (taking the trigger bar out of my .40 I was turning in and putting it in my personal .45) I was sent to the range with the supervisor.

The supervisor cracked off a few rounds to make sure that the weapon was sighted properly. He asked if I wanted to run a few magazines before I qualified. I told him, NO. Give me two or three shots to adjust to the cycling of the weapon and I am ready to rock.

Fired three rounds. Dropped the mag and went through a Qual session. Shot a 97%.

That is 97% OUT OF THE BOX.

GLOCK PERFECTION!

I bought the model with the full Pic rail and other than trying to find off duty holsters I love it.
