Nice revolver. I worked on one of those a few years ago for a friend that didn't understand that stainless steel could indeed rust! Once done cleaning up the mess, and other than it looking like it was nickel instead of stainless, it was no worst for the wear. I took it out to test fire it and it was absolutely the most accurate .357 that I have ever shot better even than my Python. Not much but still better. If yours shoots anywhere near what that one did you did real good.
