Hi, I have Shadow 2 converted to SAO with CGW Flat Trigger, Reduced Power Trigger Return Spring, floating pin. I like a bit firmer trigger, but want to lower a bit the weight of pre-travel. I do not want to adjust the trigger to remove the pre-travel completely. The trigger bar is polished, top of the trigger is polished, the insides of the frame are lightly polished. If feels very good and smooth. I just played a bit with A01 that I thought felt a bit lighter and I have an itch now to see if I can make my shadow 2 closer to perfection. I probably won't notice any difference when actually shooting, but still... I thought about adjusting the trigger bar spring and read CGW notes about it. Before I start messing with it I wanted to know if anyone had experience with adjusting the weight of the pre-travel and if I'm looking in the right direction.
