I feel your thoughts…
I have a couple chunk guns that are too long/large to fit in a safe…so…mostly displayed. When I’m home, I keep one or two out, but when I travel…back in the safe they go. I’ve thought about doing a display on the wall with a custom metal strap that lags into wall studs and locks over them making it very difficult to remove without a lot of work. Have not done it yet though, and…fire is still a concern…
If I have planned workers in my home or visitors…all go into hiding and the safe. No sense advertising… but sometimes you just gotta live... good luck!
