Trigger and Lock-Out Assembly
The safety lockout lever relies on a small torsion spring and a plastic pivot pin to maintain its 'up' position. Over time, the plastic pivot point can shear or the spring can dislodge due to vibration, causing the lockout tab to wedge permanently against the trigger's mechanical stop. Replacing the assembly ensures the physical geometry of the interlock is restored and the trigger can move freely through its variable path.
