If you cut the barrel to 4.5" you will need to do some work to make it run reliably without a suppressor. I removed more weight from the bolt than S&W did for their 15-22P pistols. It will run SV and subsonic ammo quietly. I also made a bolt buffer to use with HV ammo.

I would appreciate more info on what you did to the bolt. also what suppressor are you running and what were the instructions you provided to jpgrips for threading the barrel for your suppressor.
thanks
