The newest hide-a-gun-in-plain-sight solution from Tactical Walls is the Hide-A-Mag – a mountable magnet that can be used to retain a handgun (or anything else that is attracted to a magnet) under a desk, counter top, shelf, or similar space. The N45 Rare Earth Neodymium Magnet is strong enough to suspend a loaded handgun. The included ABS plastic cover prevents marring from contact with the magnet.
