I've got two P22's, one the standard, short barrel and one the longer "target" barrel. The short barrel one has performed flawlessly, around 20k rds through it and not a single failure to feed. The longer barrel started out a little particular and would only consistently feed mini-mags. Looking at it a there were a few spots along the rails and hammer that were a little rough. I cleaned those up and it's run over 1500 rds without a problem, even with economy high velocity ammo from different makers. You can't beat the P-22 or the Mosquito, whatever works better for you, to get lots of range time in or to teach new shooters.
