you gotta retinal scan on yer gunvault, dontcha?...
Nope, just a big honkin' high-security padlock with a Medeco key that resides in the bedside vault with the electronic touch-lock, right next to the Smith. You can buy gun vaults with fingerprint readers, though. Just a bit too pricey for me.
And I'm glad to hear the knife went to a good home. Let me know when you need more.
