Glock 19, and I'm not big Glock fan
I find objectivity very admirable. In the early 90's, I didn't care for "tupperware" for my personal defense. I was old school BHP. Then I shot a few of the G17/19/22/23 1st and 2nd gen guns. Couldn't find anything to complain about their functioning. All my complaints were cosmetic and I could not call it a "work of handcrafted art". But the second gen G19 became my go to for a step up from my pocket carry revolver to an IWB hi cap when I felt the need.
