Ah, the p-22 one of my favorite handguns out there and I dont even like handguns!
I just got a fake Scilencer for mine and not only does it look great I seem to be able to shoot MUCH better with it! I think it may have to do with the balance of it now.
Congrats on your pistol, the first 200 rounds you will get one or two jams but after that you can use cheap Walmart High vel ammo and it will eat it all day without jams.
Oh, btw Im going to try and cut and paste some p-22 mags to make a 20 round mag here for them soon with a TIG welder, once I get them working il post on here and see if anyone wants to buy some. I did it in welding school with a Marlin .22 10 round mag and it works good. <- Yeah it was after the ban expired.
