Deviant Olam is another good one for physical security. After seeing a few of his videos on gun “safes”, I looked into genuine gun safes (TRTL 30x6 or better, and/or DoD-approved weapons containers) with S&G mechanical locks, and the prices are eye watering. An S&G lock by itself ain’t too bad–about $600, IIRC–but the safe body itself was $15k+, easy. …Without shipping included, since there’s no fucking way I’m getting that into my basement myself. Most gun “safes” are not even UL-listed Residential Security Containers, and you get into $2000+ for one that meets that basic, very, very minimum level of protection. (Yes, I looked in the local gun stores that carry them.) The fact that most gun “safes” aren’t capable of resisting an 18" prybar that’s used continuously for 15 minutes is not a pleasant thought to think about.
