The Desert Eagle 357 is perfectly balanced and it enables tight groups at 25 meters in a tactical situation. The large grip ensures stability and the medium rounds combined with its efficient gas ejection system ensures that you can stay on target with a fire rate of 2 rounds per second !
The 50 cal version is too powerful and requires more time to acquire your target after each shot so it is of little tactical use.. The full on military version in the the 3rd picture can actually disable vehicles but once again it takes longer to acquire your target after each shot.
There is a 9mm version but it just doesn't have the stopping power of the 357 version and once again, the 50 military version is overkill but fun to fire. I wouldn't mind having the DE 357 as a standard side arm.
