Main thing for concealed carry, is how do you like the gun. I like glocks a lot, but maybe you don't. My dad's buddy used a glock 17 for years, it was stolen & he decided to try a newer model, it was a glock 20 something, sorry I do not remember which model exactly, but slide would come back & tear the skin on his hand. So find a range that rents them or a buddy that has that gun & run some rounds through your choices. Does it feel good? Are you accurate? Do your pants hit the floor, lol? Does the gun make you want to shoot it? Also, ammo capacity is smart. Unless you are running several thousand rounds a month through the gun & practicing for high stress situations, when you first go to push that gun out in front of you, you are likely to miss your target. More rounds, more opportunity to strike. On another note, do not ask the salesman for his suggestions, he will either give you his personal carry choice or whatever gun he needs to move or will get the best commision off of. I had a saleman tell my wife that women should only carry revolvers. My wife is a better shot than I am & she can handle shooting a 1911 .45, she just does not like them.
