If it is an FP, it should have a 3-screw trigger. That means there is a sear depth screw, as well as a safety adjustment screw, and an overtravel screw. Change out the external wire for a music wire of about .040 in. Then adjust the sear screw in to reduce the engagement. Next reduce the overtravel. Finally, make sure the safety still works properly. If not, adjust the safety screw until it does. Test it to be sure it isn't too light by bumping the pad against the floor several times. If all is good, coat the screws with fingernail polish and you are done.
