What do you want to use it for? 9mm is cheaper and much more pleasant for target shooting IMO. Not as loud, not as much kick, cheaper bullets. I love my 9 MM Glock 17. My favorite gun to shoot hands down, but I have really large hands and people with smaller hands seem to have trouble with it jamming (has never jammed once for me). Probably the thing to do would be to go to the gun store and hold a few of them and see what fits right in your hands.
