Hi Steve,
To adjust the trigger on an LP53, you have to back the adjustment screw lock-nut off, so that the actual adjustment screw can be turned. Once the trigger is adjusted to your liking, the lock-nut must then be tightened up again. The little screw in the center is the adjusting screw - the lock-nut is the collar with the two slots in it that surrounds the adjusting screw. You may have to modify a standard screwdriver bit, if you do not already have the necessary spanner-type bit to fit the lock-nut.
Regards,
Len
