ABSTRACT:
Disclosed is a barrel lock to be removably inserted and reliably locked within the barrel of a hand gun to prevent the accidental and unauthorized firing of the hand gun without requiring any manufacturing changes to the gun. The barrel lock includes an expandable chamber lock that is located at the distal end of a barrel lock tube. The barrel lock tube is adapted to slide inwardly through the gun barrel to locate the chamber lock to be received in and retained at the existing bullet chamber of the gun barrel, whereby the hand gun is disabled. A combination lock cooperates with the proximal end of the barrel lock tube to prevent the barrel lock tube from being withdrawn from the gun barrel and the chamber lock from being removed from the bullet chamber until a particular predetermined combination has first been successfully dialed in.
