I have the above mentioned 22LR pistol. I have been extremely happy with this 22 pistol. I now have a suppressor for is and I switched to a threaded tactical solutions threaded barrel. I am having major fun shooting it. It cycles well even with plain 22s. I have bought a couple boxes of subsonic CCI and it will not cycle. I did not expect it to I have been shooting as a one shot. Anyone here done any mods to theirs to get cycle a subsonic round .
