Abstract:
1. A trigger lock for use with a firearm having a firearm body, a barrel, a trigger, a handle behind the trigger, and a trigger guard with an opening surrounding the trigger, the trigger guard having a front portion closest to a firearm muzzle and extending downward and away from the barrel, the trigger guard having a bottom portion furthest from the barrel, the firearm having a transition step leading from firearm body to the trigger guard where the transition step delineates a decrease in cross sectional thickness from the firearm body to the trigger guard, the transition step having a top transition step contour closest to the barrel and a back transition step contour closest to the handle, the trigger lock configured to receive a lock, the trigger lock comprising: a shield member comprising a first flange, a second flange spaced apart from the first flange, and a web connecting the first flange to the second flange, the first flange having a top edge and a back edge; a first aperture being formed through the first flange and a second aperture being formed through the second flange; and a plug with a base having a shaft extending from an end of the base, the shaft having a lock attachment portion; wherein the shield member is configured for engagement over the trigger guard, with the trigger guard inserted between the first flange and the second flange to cover the opening of the trigger guard; and wherein, when engaged, the web is configured to cover just the front portion of the trigger guard leaving the bottom portion of the trigger guard exposed; and wherein the plug is configured to be inserted through the first aperture, passing through the opening in the trigger guard between the trigger guard and the trigger, and through the second aperture, the base of the plug being positioned closely adjacent to the front of the trigger guard such that the front of the trigger guard is closely bound between the web and the base; and wherein the top edge of the first flange contacts the top transition step contour to substantially prevent movement of the shield member in an upward direction towards the barrel, the back edge of the first flange contact the back transition step contour to substantially prevent movement of the shield member in a rearward direction towards the handle; and wherein the lock attachment portion is configured to receive a lock, the lock once attached being sized to prevent de-insertion of the plug, the shield member blocking access to the trigger preventing user actuation of the trigger.
