I bought a Browning shell and built my own shelves inside so I could configure it the way I wanted. This worked great for a while, but then had to get another one. Now I have two that are full and a gun case that is overflowing. So get as large a one as you can afford and have room for, and if you get a fireproof one, you can also store valuables and important papers (until you need the room for more guns

)
