Hi,
I have been reading on here where people are advising against changing the recoil spring length on P22s because they are engineered correctly and feeding issues are likely ammunition issues. While my P22 recoils and operates just fine with many brands of ammunition, when I put the suppressor on it and fire it with subsonic ammunition, it doesn't feed properly and is essentially a single shot pistol. I thought about cutting a link off at a time until it cycles properly and using that spring for subsonic loads when shooting through the suppressor and keeping a second spring for normal rounds. What are your thoughts?
Thanks.

I think you could play around with it a bit. Years ago I cut coils 1/2 at a time until there was just enough energy left to reliably close the slide but you might run into problems here with a weakened spring since the suppressor gets the pistol really dirty really fast. There is considerable drag of the feed rail across the hammer face as the slide closes. Do you have the original long spring or a later captive spring. Same spring as far as I can tell but late pistols come with the captive spring. I think the Sig Mosquito came with a target ammo spring and regular high velocity spring but the pistol still had issues as I recall. Let us know what you come up with if you will. 1917
