FYI, I recently ran into something called the Quick Draw Gun Magnet sold by Arizona Armor. It's a powerful plastic coated magnet with a grommeted base that can be fastened either by screw or nail or with velcro to attach a firearm just about anywhere it will fit. I've got one in the side pocket of my pickup (with velcro) and on my bed frame (without). Keeps your firearm close by and handy without marring the finish. I'm sure the members here can think of a zillion ways to use this clever device. It's on display at Arizona Armor. And the folks there are friendly as can be. Good people.
