ABSTRACT:
A high security gun lock device is disclosed which has an elongate gripping and locking assembly that is inserted into the muzzle end of the barrel of a revolver or pistol type hand gun and which is then connected to a dummy round located in a cylinder chamber of the revolver or the firing chamber of the pistol. The dummy round has a bulbous head which is grasped by a plurality of expandable gripping fingers mounted on the inner end of the gripping and locking assembly to lock the latter to the former. An axially slidable actuating mechanism is manually operable to cause the gripping fingers to release the bulbous head of the bullet, and a spring biased interposer is normally operable to prevent movement of the actuating mechanism until a locking mechanism is set to a predetermined condition to permit operation of the interposer. The locking mechanism has features of construction which permit it to be manually operated solely by tactile perception of relatively movable parts, thereby allowing the gun lock device to be operated in the dark. An enhanced version of the dummy round provides for axial elongation and radial expansion of the bullet so that it jams in the inner end of the gun barrel if any attempt is made to forcibly removed the gripping and locking assembly from the gun without properly unlocking it.
