Get the keypad. Believe it or not, I had a S&G dial lock foul up. It became nearly impossible to open, like there were marbles in the works. (browning safe). We changed it to digital S&G. My friend, my bro, and myself all have digital. One better is a double door with two digitals. Failsafe. Dial locks blow if you get into your safe several times a day. My batteries lasted two years, and they have a low battery warning.

These are safes, not gun cabinets. If your "safe" says RSC on it, it is rated as a "residential storage container" by the Underwriters Laboratories. It is, by no means, a safe. Many unwashed can get into a RSC with a sledge hammer in less than 5 minutes. I discussed this with an appraiser who deals with gun thefts and insurance companies. He has seen several RSC's defeated and explained some of the process to me. Very enlightening.
Look carefully at the Canon's construction. Some of them suck. If it is a hidden hinge with only two points of contact, one at the top, one at the bottom, this is the easiest of all to defeat. Simple mechanics. I am aware of the design features, because I play an engineer on TV, and I was going to build my own safe. Dollar for pound, you can't beat the Brown.
