Unfortunately, I haven’t found a biometric wall safe capable of storing shotguns and rifles ( of course, that’s not to say for certain that one doesn’t exist), but the V-line “closet vault” is a button combo operated lock, and can be easily mounted on a wall or within the studs. They’re a little pricey (~$550 neighborhood), but the couple people I’ve talked to who own them seem to like em’ a lot. Hope that helps – thanks KJ!
