ABSTRACT:
A gun lock consisting of three parts which engage each other to provide a shaft extending through the gun barrel and the bullet chamber, the shaft being held in position by means of a combination lock. A dummy round occupies the bullet chamber and has a hollow cylindrical front portion with a groove for engaging the locking balls which are disposed on the inner end of an intermediate rod which extends through the bore of the gun barrel. The intermediate rod has a slideably moveable central actuator with a cam end portion for forcing the locking balls radially outward to engage the groove of the dummy round, and semi-circular recesses into which the locking balls can fall when the actuator is pushed in to permit insertion or removal of the intermediate rod. The combination lock secures the actuator to prevent it from being moved inward to release the intermediate member from the dummy round.
