Most subsonics function fine in my 10/22 and 22/45. Super colibri's will not though but I think those are something entirely different. With a 10/22 or 22/45, if you planned on shooting subsonics frequently, you could change recoil springs to allow proper cycling if you were having issues.
Due to several differences of opinion with staff, I am choosing to no longer do business on this forum. Everyone that has a pending order will need to contact me via email at TakticalHolsters@aol.com
