I've used them - no problem. After too many years of gun safes and not getting to enjoy the look of the functional art contained therein, I finally built a secure gun room. No gun has to hit another just to pick it up and replace it. I did keep the safes for ammo and somehow one has started to accept some permanent residents. If you get the opportunity to build a secure gun room, best to make it bigger than your first thoughts - if you can. Maybe should have stuck with safes and socks
