Shorten spring for suppressor

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.
