Short Answer; Shoot It As-Is.
I have come to realize that guns with condition problems are the perfect guns to shoot and enjoy. I can take out this late S prefix 29-2 and not worry one bit about scratching it, getting caught in the rain, etc. At some point in its life someone must have done some shooting/hunting and was caught in a light drizzle and left in a holster for a day or two afterwards. It has small, smooth specks of missing blue ALL over it! Looks good from 10 feet but not so hot up close. But guess what, I love this revolver! It now sports a set of John Hurst target stocks instead of the rubber.
Accurate and Ugly is a pretty good combo for a hunting/range revolver.....
