I have a special loathing for P22s, as the placement of the mag release as a part of the trigger guard, results in my being unable to fire the damn things without inadvertently dropping the mag at least fifty percent of the time. I have met one other person that this happens to, and he is a giant burly man, whereas I am a five foot tall woman. To the best of my knowledge there isn't anything I do wrong; it's just a personal idiosyncracy.
What I'm saying is, do your best to rent one for an afternoon and see how you like it.
QFT. I've had a lot of people including myself drop the mag while we were shooting it. I don't have a ton of problems with jamming or anything, but like others said, it's really just a plinker. I got mine when it first came out and only had to pay $215 for it though, which I feel is a much better price than the $350 it is now, that's just too much for not enough gun.
I may even buy another semiautomatic assault weapon rambo killing machine for my small penis, with lots of large capacity non-reusable clips full of armor piercing incendiary mercury tracer poisoned explosive hollowpoint glaser black talons
