I recently picked up a used 4" Ruger Security Six in pretty good shape. I used to own a 6" and I always wanted another in 4" for ease of carry. I've added a Hogue rubber Monogrip, stoned the action so that it is much smoother, and toned down the finish to a smooth satin with a Scotch Brite pad. I then put in a new white-outline rear sight blade and a bit of white on the front sight blade. All in all I'm very pleased with this revolver. No problems shooting into 2" at 25 yards with factory 125's either.
So now that I have it darn near perfect, I want to make it even better. Specifically, I'd like to remove a little of the minor cylinder play. There's a little more lateral play than I would like but short of getting a wider pawl to fit the cylinder slots there's not much I can do to change that. Since there's no evidence of lead shaving at the rear of the barrel, I'm not much worried about it. But there is a little bit of fore-and-aft play that I was wondering how to address. Are there cylinder shims available to address this? I was hoping that I might close the cylinder-barrel gap in the process.
