When I clean my CVA Accura MR, I always remove the bushing, firing pin and spring and clean the parts along with the hole. I put a smidge of anti-sieze on the bushing, re-assemble and do the firing pin, trigger, hammer test to verify firing pin is free to move in and out.
A friend of mine has a CVA Wolf and has never removed the bushing to clean the firing pin and spring. He’ll have an issue some day and the bushing will probably not come out very easily. Not sure why he doesn’t take a few minutes to clean it.
