I used to just keep my CCW on the headboard at night (it goes with me when I leave the room). My little one turned 1yo in December though, and is a running, jumping, climbing, whirlwind of destruction. Leaving it on the headboard just isn't an option anymore. After reading a lot of reviews, I opted for the GunVault SV500 with the keypad (I don't trust the biometric scanners). I don't have a nightstand on my side of the bed, so I mounted it to a stud inside the closet, about 3 feet from my side of the bed. Now I keep my CCW in the big safe downstairs, and a .45 permanently lives in the GunVault so it's always there in case the wife needs it while I'm at work. I've had it since October; I test it once a week, and it's been flawless so far.

TL;DR: GunVault SV500 with keypad, mounted to a wall, out of sight, but within a few feet of my side of the bed. Test often. Works great.
