Lighten A Trigger Pull

The pull strength of a trigger varies from gun to gun.

Gun collecting and shooting is a favored pastime of many people throughout the world. Like equipment for other hobbies or sports, each participant prefers a certain type of gun, and certain specifications for each. Trigger pull is one of those specifications that vary from person to person. Manufacturers tend to install a pretty heavy trigger pull on their weapons, meaning that it takes a fair amount of pressure on the trigger to fire the gun. This high trigger pull rate can reduce the chance of accidents. However, some experienced shooters prefer a lighter pull, and with the right tools and techniques users can lighten the pull on their triggers.



1. Make sure that your gun is not loaded; never try to make adjustments to a loaded gun, or else you risk injuring yourself or someone nearby.

2. Lay the gun in front of you so that the barrel is facing your right. There you will see three screws: the bottom left is the engagement screw, the top right is the over travel screw and the bottom right is the trigger pull screw. Determine what type of screw driver you need for the job (straight or Allen head) and have that at hand.

3. Scrape away any glue or adhesive that is holding the screws in place with a plastic or metal scraper. Remove as much adhesive as possible to make moving the screws easier.

4. Place one to two drops of gun oil over the screws and unscrew them, moving them in and out of their holes a few times to thoroughly soak the threads in gun oil. This will make your adjustments later much easier to handle. Replace the screws to their original places once they are coated in gun oil.

5. Pull the trigger pull screw back out of its socket slightly. Test the trigger pull as you go; pull it back until the pressure on the trigger is very light. You will adjust this level to your preference later.

6. Unscrew both the over travel screw and engagement screw four to five turns to allow for some adjustment and movement freedom.

7. Close the bolt on the top of the gun, but do not pull the trigger. Slowly screw the engagement screw back into its socket. Continue to push on the engagement screw until the firing pins drops into the fired position. Back the screw out by 1/3 of a turn and tap on the trigger; it should wiggle back and forth easily.

8. Screw in the over travel screw slowly, until it just touches the trigger very lightly. Back the screw out by 1/4 turn; this should prevent the trigger from wiggling as it was before.

9. Turn the trigger pull screw as tightly as you prefer for your trigger pull strength; test the pull with your fingers or with a pull gauge to make sure you get your preferred pull strength.

Safety Check

10. Open and slam the bolt of the gun at least 12 times, checking each time to make sure the firing pin does not drop; if it does, the gun has misfired. If the pin drops, pull the engagement screw out 1/4 turn and try again, until the firing pin does not fall.

11. Cock the gun and set the safety, and then pull and release the trigger. Release the safety. Repeat this check at least 12 times to make sure the firing pin does not drop with the safety on; if it does, the gun has misfired. Tighten the trigger pull screw by 1/4 turn if the pin does drop and try again, until the firing pin does not fall.

12. Coat the screws in red or white nail polish, allow the coat to dry, and then apply a second coat. This nail polish will replace the adhesive that you scraped off earlier, securing the screws in their new setting.
