Just installed something on the door of my gun safe. Bought it on Amazon it's called snapsafe door organizer. It's made out of plastic covered wire shapes roughly like a ladder it comes with small baskets that attach and it drills to the top of the overhang on your door. You can use it as it's designed or I found out that clip on holsters fit on all the wires. The best part is on Amazon it's only $23 and change.
