There are two adjustments to be made.
1. Loosen the top single nut and adjust for overtravel and lock screw.
2. Loosen the top nut on the two lower nuts and adjust for weight of pull, when you feel comfortable with the weight of pull lock the nut's in position by turning the top nut down. If lighter pulls are desired you have to change the spring or bring your gun to a knowledgeable gunsmith to fully adjust your trigger.
3. Sear engagement can only be done by a qualified gunsmith since material removal is involved. I don't reccomend you attempt this yourself.
