I have the GunVault Multivault
pistol safe and have been very happy with it. I've got it bolted to the top of my gun safe so it can't be carried off. You enter a 4-digit combination and the door of the safe springs open into your hand.
I have four pistols, some mags and a dessicant pack in mine, so you might want the smaller MiniVault instead of the MultiVault.
