Having issues with random fail to fire in a UC9 Uzi . Every 40-50 rounds I will get a light primer strike. I took the grip off and from what I can tell when I pull the trigger it seems sluggish.Does The front hammer or sear pin need to clear the grip safety bar or does it ride the "notch" ? Also how strong should the sear or most forward spring be? It seems sluggish on release and does not move quickly like an AR. Thanks in advance
