Anyone know about S&W stainless finishes? I'm getting a 627 PC V-Comp V8 in a few days. (Hope I don't regret this) But while looking at it I noticed it isn't as shiny as my j frame in stainless. It is more of a matte finish. I know anything from S&W with a model number starting in a 6 means stainless. Can these be polished or is that a special coating?
