Measure the height of the sear above the top of the trigger frame using the highest point as the reference (measurement "A"). Subtract 0.075 (roughly 5/64") from the "A" measurement to get a result "B". The new "B" number is the depth to set the 10-32 Allen screw that is screwed into the hammer, through the slot on the bottom side of the gun body. This measurement is taken from the bottom of the body to the top of the 10-32 screw. Note : If the screw needs to be shortened, do not grind the exposed end. Remove the screw and grind the tapered end.

EXAMPLE: If A = 0.125 (1/8"), then 0.125 - 0.075 = 0.050 (roughly 3/64") which is "B"
