I went thru this process umm last year or so. FWIW IMO the best safe I've considered is made in Elm Mott Texas, on I-35, just barely north enough of Waco enough to have it's own exit off of I-35. Can't pull the name this early in the morning but Google is your friend....and what I will buy after finishing the reno on this old house house
Uses a double key entry, with the keys inserted vertically inside an inset in the door, into the locks that are facing down and behind a panel of work hardening Steel that resists drilling the locks.
These are a low volume made on site item, and can be customized completly for Fire rating and additional steel protection, with enough different sizes & standard trim & layout levels to satisfy 98% of folks....before you get into the full custom stuff. You want it, they can build it.
Saw lot's pics on line of battery locks push button gun safes with plastic running down the face of the safe after a fire. S&G dial locks are the industry standard.
But whatever you buy, placement and fastening the safe securely to the concrete floor will help with the #1 entry by bad guys, who either turn the safe on it's back and use a pry bar or beat the door open with a sledge or simply use a powered saw to cut the front of the safe off just behind the front door hinges, which is the other soft spot in volume production safes.
PM me for a Dealer Contact that will help you with an order, when you bill your safe thru him.
