I must admit I am a glock guy. I like the G19 frame size the best which I have. I wanted something in the 40 s&w and was looking at the G23 gen 4's. Same size as my G19 so holsters would fit both guns etc. Well I have owned H&K's in the past along with alot of other firearms. A while back I had a H&K uspc 40 and ended up selling it big mistake. I really think the uspc handles the 40 s&w round better then the G23. Just my opinion so I ended up ordering a new uspc this afternoon can't wait to get it. I'm not going to let this one go.
