Unless you got some big ol hands, you won't like the fat Glocks in .45ACP (models 21, 30 and 41).Call me crazy, but I want a Glock in .45, a lever action 45-70 and a semi auto .22 pistol.
The Glock 36 is a goodun, if you don't mind the finger grooves. I woulda kept mine if they didn't have those.
I'm a Glock guy first and last, but if you really want a striker fired. 45, give the Smith and Wesson M&P 45 Compact M2.0 a try. I absolutely love mine. It feels awesome!
