^^^^cool. THat was my original assumption when you first said you were getting light strikes. Sometimes, though, people assume that's their problem when in fact they are not getting any strike due to shooter error with the Accutrigger.

But, for the benefit of others reading this thread in the future...

You were CERTAINLY getting some drag on the firing pin due to interference which lightened the strikes. On OTHER occasions, there was likely another issue with the shooter not pressing the Accutrigger properly. In those situations, the trigger was not dragging, it never had a chance to drag. The sear was getting blocked by the safety blade in the trigger as per it's design.

Glad you got it resolved. Sorry if I am beating a dead horse, don't mean to. Just trying to help other readers in the future.
