I have a S&W M29-M2 44 Mag with 6.5" barrel. Showed it to a friend of mine years ago. We was eating potato chips at the time I showed the gun. After looking at it, putting it back in it's case without wiping it off. I forgot about for a month. Took it out of the case to check it out before I go to the range with it. You could see where the finger prints was, because of the rust spots. Everyplace a rust spot, was a finger print.
