A versatile high security mounting system which allows a 12" or 16" x 3" model handgun case to be mounted to the wall or floor. This provides excellent security to the owner by providing a means of mounting their case to the interior wall of a closet, on the floor next to their bed, or under the bed. All mounting hardware is out of sight under the case and can not be accessed unless the case is removed from the plates. The system uses the interior side lock of the case to secure it to the mounting plates so no other lock or key is needed.
