I own a couple revolvers. An S&W 66 (with hole) a 629 (no hole) and a Ruger super red hawk 454. About a year ago I sent the 66 in the S&W performance center for there master revolver action package. This included the following: Trigger stop, chamfer charge holes, polish rebound spring, hammer stud and yoke barrel bosses, detail lockwork surfaces, stone hammer and trigger contact areas, test fire for function. This improved the trigger a lot but it could still be sweater. I have been wanting to have some work done on the 629 and super red hawk. I recently purchased the “Trigger Job DVD” from GunVideo. In it Jerry shows the stoning of a few surfaces that smith did not do. He also installs a new trigger rebound spring and main spring. (These require federal primers). In the next couple of weeks I am thinking of working over the 629 depending on how that goes I might do some more work on the 66. (I may even tinker with the Ruger. Is there a good source on Ruger trigger work out there?) Does anyone have any tips for messing with the 629? What do other folks use for springs? I do mostly double action shooting. I carry the 66 a lot and the 629 is my woods gun so I would want both to be 100% reliable. I also want both revolvers to feel very close to one another, so that practice with one carries over to practice with the other. What do you think of this and what do other folks do?
