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 20):
The device of  claim 15  further comprising a small soft metal bushing located proximal to the notched disk arranged to occupy the distal bore of the barrel that is proximal to the muzzle, wherein the soft metal bushing serves with the notched disk to center and stabilize the firearm within the cavity of the lock housing during activation, eliminate looseness and protect distal and internal surfaces of the barrel, including the crown, from abrasion and damage.
