To be fair, my PF-9 couldn't hit crap on it's best day.
That said, that thing doesn't look particularly small? or is it just how disproportional the slide looks to the grip area?
Inanimate objects don't have good and bad days. People shooting guns do. I still think the G23 is one of the best all-around CCW pistols. I can't shoot it well, so I don't have one.
The P15 is not small per se. It is a medium sized pistol.
