Well,
I hope you have better luck with feeding with the G22 than I have ever had with my P22.
Basically, the thing I can do to make my P22 happiest (that means minimizing, not eliminating) jams is to feed it CCI Blazer 22LR ammo. It seems to only jam about once or twice every 50 with that ammo. Some ammo it jams every other (if I get lucky) shot.
