I installed a new trigger that I received from a reliable manufacturer of AGD parts. The trigger design mirrors that of the original trigger for hinge, tab, and magnet locations. With my original trigger, when I pull my pin it says AGD 3.2 and is live to cycle the marker. HOWEVER, I installed the new trigger and once it was complete, I pulled the pin and instead of the usual AGD 3.2 and goin live, it had two dash marks and that was it. I reinstalled the original trigger and its business as usual.
