I would recomend that you get a "fire rated" gun safe. The ratings of course vary in duration (30 mins up to 60 mins +), and the price flunctuates with that as well. Don't get a walmart gun safe, they very likley will not survive a tool attack. My first safe was a Morgan Fort by Browning a 9 long gun safe with shelves. In 2001 My home was broken in to for the express purpose of breaking into that safe. It survived a horrendous tool attack and they couldn't get the thing more than 6 inches from the wall. It survived crowbar prying on the corners of the door, beating on the hinges with a sledge hammer, beating on the edge of the safe to try to crack open the welds, beating the handle assembly and lock completely off the safe, and removal of the safe (it took 4 of us to get the thing inside my home empty).
I had to hire a locksmith to open it for me and it took him a little over 2 hrs to drill through the hardened steel, in just the right spot, so he could trip the lock and get the door open. Nothing else in the house was touched! Laptops, TV, all left alone!
Get a bigger safe than you think you'll need. It will fill up fast I promise you!
