I have a model 19 that was my original issue when I went through the police academy in 1975. I carried the revolver for about ten years before we switched to the 659. During the years I was carrying the 19 in a leather duty holster a good amount of blueing on the barrel, cylinder and frame wore off. There's no rust on the gun as I take good care of it, but I'm thinking about getting it re-blued but I didn't know if it would hurt the value of the revolver. I would never sell it and plan on passing down to my son. I'm close enough to Springfield that I can run the revolver to the S&W factory to have the blueing done. What say you? Reblue or leave it as is?
