How to set up for sub sonic ammo

618 Views 4 Replies 4 Participants Last post by  Jeffrey
Does anyone have a good working combo they can share with me?

I would like to modify my P22 to cycle perfectly with quiet ammo (CB Longs?/suggestions?).

I have read on other guns guys modify recoil and hammer springs, and polish stuff for smooth operation. Has anyone successfully tried this on a P22?
