Yeah, at 745lbs, that's pretty light. My 19 year-old, 25 gun Liberty safe is less than half that size and weighs 700lbs empty. I couldn't find in the specs anywhere that it has a 10 gauge body either. Show me if I'm wrong but I'd be VERY surprised if that's the case.http://www.tractorsupply.com/tsc/product/cannon-ts5950-75-safe?cm_vc=-10005
not your traditional place to buy a gun safe, but, this one is NOT light, 800 pounds, 10 gauge steel, advertised as 80 gun capacity. definitely growing room.
