Recently my FX Dreamline Tac Compact started to not cock at times. I recently noticed this when trying to get a lower power tune with lower hammer settings. I am not sure if the lower hammer settings were the problem as it happens sometimes too at higher settings too. The thing is if before cocking if I pull the trigger all the way back then release it will then subsequently cock. I am assuming I need some more spring tension on the trigger but which screw would I adjust if that is the problem. Bill
