Surprisingly this is actually my first post on THR. I look at articles and forum entries on THR all the time, but never took the time to register until now. I am an extremely die hard Glock collector, but about a month ago purchased my first revolver which was a GP100 stainless model. It is a newer model with the brushed stainless and the hogue finger groove grip. When I first got it, I kept it in its hard plastic foam less case, but I then put it in a gun rug while I went on a trip (it traveled with me). I tonight JUST pulled it out of the gun rug and it had a little tiny almost microscopic amount of rust on the side of the barrel. No big deal as it came right off with some Mothers Mag polish. My question is, is that I know stainless revolvers are very rugged, but that NO gun should be left in a foam padded case or gun rug for extended periods of time. Will I be ok with leaving it in the hard plastic case since there is no foam inside to attract and hold moisture? I have only owned Glocks, so am a little new to the whole bare steel idea. For what it's worth I love my GP100!
