Zapper,
The guns that get used frequently do show some slight wear to the bluing on the ends of the bbls but I have experienced the same & much worse wear with zippered cases & slips. Unfortunately it's something that is going to happen with a reasonably tight fitting slip & frequent use & I'm most interested in preventing deep nicks & gouges.
The Murray slips are lined with a synthetic fleece & at first I was concerned about it re. picking up grit & moisture retention but these concerns proved to be unfounded.
I've experienced no corrosion issues but I'm careful not to put a wet gun in the slip & on the rare occasion I've got the slip wet I use the wader extension on my boot dryer to get it dry.
Obviously, I don't leave guns in the slips any longer than I must.
Re. embossed labels & matching accouterments, I don't remember if the Murray cases have a label & my luggage is usually a pair of canvas duffle bags I bought from Gander Mountain in 1970 w/my ID elegantly put on with magic marker so the Murray slips definitely don't match.
