This all looks good. Old Corp - I like the crown royal bags and hope to pick up some on New Years Eve! I haven't tried it yet but a lot of gun shows show their guns displayed vertically supported by wooden dowels. The barrel of the gun goes over the dowel. This could be a worthwhile option.
I'm also thinking about using some rare earth magnets attached to the side of my cabinet. The ones that have a hole in the middle and can be attached with screws. I'll use this to hang my flat pistols like Glocks and CZ's. But someone asked me if the magnetic field would magnetize the gun I don't know..........about that.. any takers?
