For extremely fast shooting, I'm pretty sure there is a benefit of having a compensator on a .22LR. Reduces recoil, and adds a little weight to the muzzle, allow you to stay on target after each shot.Why would you want a muzzle break on a .22? There isn't enough kick to break a test tube. The 22/45 is an excellent pistol as is and I personally think that adding a muzzle break isn't going to improve accuracy at all. If you want to get any better performance from it, then 'maybe' rework the trigger spring tension and 'possibly' slide spring tension. Personally, I wouldn't mess with the slide spring at all. Ruger is very good at designing what they produce.
