I love my Fort Knox with simplex lock system and craftsmanship if top notch. They are little more expensive but he steel is very heavy 10 gauge with 3/16" full wrapped over hinges door, powder coated, hydraulic strut to help open and close it. The safe holds my Ccw weapons, 5-6 sometimes depending on arrangement . It now has a 3" 1911, Two Glocks 19 and 27, wife's shield plus three of four mags for etc weapon. This is where I grabbed mine from and not sure if it's a site sponsor so I'll leave link cold so you have to copy and paste it. Cheapest place I found them at http://www.deansafe.com/ftk-pb.html?gclid=CJDEzMXdkcECFajm7AodoV8Axg
This is picture of mine with tape measure diagonal but I lay a couple pistols in bottom then layer of foam and more used pistols on top.
