Abstract: A security device for safely storing firearms is disclosed. When a firearm is locked to the device, removal of the firearm from the device and removal of the device from the mounted structure are prevented. In the preferred embodiment, the device comprises a disc-like base member, two rods secured to the base member and extending therefrom, a disc-like covering member having two holes therein into which the two rods are inserted and from which they extend, and a hole in the end of one of the rods for receiving the shackle of a padlock. The firearm is secured to the device by placing it on the device with the trigger guard extending about the two rods and the trigger disposed between the two rods. The padlock is then attached to the device to prevent withdrawal of the firearm. The firearm can not be discharged since the trigger is prevented from moving by the two rods. The covering member prevents removal of the device from a wall or a locker, for example.
