US12352519 - Loaded-chamber indicator firearm trigger device

A loaded-chamber indicator firearm trigger device is provided. The device is comprised of a firearm with a trigger (or only a trigger in one embodiment), wherein the trigger is comprised of an exterior side surface with at least one indicia. The indicia is only visible outside of the frame of the firearm when the firing pin of the firearm is engaged (which causes the portion of the trigger the indicia is positioned on to move outside of the frame of the firearm). As a result, the observability of the indicia on the trigger indicates the firearm has an engaged firing pin and is ready to fire.
