I've never owned a Glock. Shot them, but I don't see all the fuss. If I was going to pistol of similar concept I'd recommend what I currently own. The Walther PPQ. I've been shooting for a good while and I know a few guys using theirs in competition and doing very well. Hands down its one of the finest off the shelf pistols I've ever shot. The trigger is phenomenal. That said, I still prefer my custom Kimber Raptor II. I'm balls on accurate with it.
Folks can get in to a number of debates about caliber, precision, reset, ergonomics, but at the end of the day it's what your comfortable shooting and train with. If your a hardcore Glock fan I can't say I'll honestly knock you. It's just not my preference.
