A subcompact P10C would be great and I'll buy it.
I figured out how to make the P10C do what I want despite the trigger. I started pressing in with my palms. I was already doing a hard push-pull with tight pinky fingers and locked wrist. The POA is also the top of the sight, not center of the dot. It was hard to figure out due to bad glasses and the small gaps between posts. Got it shooting now.
These are quick 10 round groups at 5 yards:
