Brother Hondo44, did you like my technical term, GRUNCHY? I agree that a good cleaning is job one to get rid of any snot and dandruff that is causing drag. Another oft neglected step is to polish the rear (bearing) surface of the rebound block. That usually helps and requires no special skill or tools if you are able to take it out to replace the spring anyway. Other than that, any polishing and grinding should be left to an expert... I'm not being snooty, it's just too easy to mess up if you aren't sure of what you're doing. BTW, long use and repeated functioning usually makes these revolvers smooth out anyway, so I'm guessing clean and with the new springs it should be a lot better.
