Abstract:
A device for controlling access to a firearm having a barrel with various physical features proximal thereto, including a muzzle device. The device includes a lock housing with a cavity to receive the barrel. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the barrel of the firearm. Embodiments described include variants on the use of a plurality of tabs such as arm, tab, and/or housing configurations to receive and grasp the muzzle device, firearm fixed front sights, bead front sights and/or accessories such as, for example, Picatinny rails, vertical or near vertical serrations, cuts and/or grooves located on the distal lateral and ventral regions of the frame and/or slide.

Claim (Index 1):
A device for controlling access to a firearm having a barrel with a muzzle device coupled thereto, the device comprising:\n a lock housing with a base component coupled to a receptacle component, wherein the receptacle component includes a cavity configured for insertion therein of the muzzle device and at least a portion of the barrel; a key structure coupled to the base component of the lock housing, wherein the key structure is arranged to receive a key; a lock mechanism coupled to the key structure and arranged for actuation by the key; a lock mechanism shaft coupled to the lock mechanism and configured for rotational movement upon actuation of the lock mechanism; a cam having a distal end and a proximal end, wherein the distal end of the cam is in contact with the lock mechanism shaft such that rotational movement of the lock mechanism shaft causes axial movement of the cam; a bidirectional rotatable shaft coupled to the proximal end of the cam and arranged for insertion into the barrel of the firearm; a plurality of arms coupled to a perimeter of the cam and arranged for pivotal and radial movement to secure the firearm muzzle in the cavity of the lock housing; and a plurality of tabs arranged on the plurality of arms for engagement with an exterior surface of the muzzle device to retain the muzzle device within the lock housing.
