I have two gun safes because I outgrew the first one I got within a few months. Now I'm outgrowing both. Go larger than you think you need!
Browning Pro Steel safes are awesome. Also have a Liberty, but much prefer the Browning!
ALSO, I bought my Browning with an electronic touchpad lock. Bad move! Dial is much more reliable! The touchpads are made of plastic and will melt in a fire. Not only that, but they are removeable to replace the 9 volt battery and anyone can cut the wires and you won't be able to open your safe. Dial lock is fail safe!
May God make smooth the path you follow!
