US12435940 - Trigger assembly having a secondary disconnector

A trigger assembly for a firearm includes a housing with an opening adapted to receive a trigger bar guide portion of a trigger bar. The opening includes a ridge that extends downward from an upper surface of the opening. The trigger bar guide is forced downward in the opening by a connector as the trigger is pulled to cause a first disconnect of a striker resulting in a first firing. Upon release of the trigger the trigger bar guide moves upward and upon return to a released position is forced downward to cause a secondary disconnect of striker resulting in a second firing.
