Standard capacity magazines and balance
There are plenty of firearms out there that can handle magazines that have a higher capacity than the standard magazines, and in most cases, I really don’t understand why anyone would want anything protruding out of the bottom of a handgun. I’d rather have an MP5 semi-auto than a Glock 17 with a 30rd magazine. I’ve seen some of the full auto Glocks, but they are nothing more than an assassin or a nose maker for most purposes. I’ve always liked 1911 handguns, and I’ve shot a few auto ordnance guns that were similar, but were double stack 45acp magazines, but the guns were just too heavy for me to wield one handed.
There is something to be said for handguns and how they are balanced out. If the gun feels like you are holding a bowling ball you’re not going to be very smooth in engaging multiple targets. Just like someone who is using a 44 magnum Desert Eagle, you get a lot of bang, but what is your hit ratio? Can you carry something like that in gun holsters? I’ve done one too many tests with new shooters and 7.62×39 AK rifle and compared bullet hits with an M4. Ever single time I’ve done a comparison people shot the better with the M4. I’ve also done comparisons with extending magazines in 9mm and 45acp and there is a certain point, guns get too darn heavy.
