When you get a safe, get one twice the size you think you need.
Twice hell, get one 5X what you need. they fill up quick.
I just couldn't bring myself to get the cabinet. I wanted a safe. That way I have peace of mind. 480 lbs, Sentry Safe, 24 gun for $675 OTD. (local friend/lgs)
My advice would be look for a good used one and atay away from digital locks. I picked up a Browning ProSteel Medallion 28 gun safe for 650 bucks off CL. Guy Paid almost 3 grand for it new. it weighs about 600-700 pounds. it was a blast to move with two people.
