Pre-Travel Adjustment Steps:
(1.) With the trigger and trigger bar sitting in the trigger tool, push the trigger bar up all the way possible.
(2.) Then insert and begin rotating the set screw. Once you feel the screw make contact with the trigger bar; give it one or two more rotations.
(3.) Install the trigger assembly back into the firearm and test the trigger pull.
(a.) If you want to get rid of a little more pre-travel, take the trigger assembly back out of the firearm and tighten the set screw 1 or 2 more times. Repeat this process until you are satisfied with the amount of pre-travel.
(b.) If the safety blade starts hitting the frame when you pull the trigger, the set screw is too far in and needs to come back out slightly.
- Loosen the set screw 1 or 2 times until the safety blade clears the frame correctly.
The Trigger Safety's intended function is to stop the trigger from being pulled just before the trigger bar engages with the safety plunger, which prevents unintentional trigger activation. It always needs two forms of safety engagement.
