The FIRST Trigger Plot

The Red Line is BEFORE Trigger Job
The Blue Line is AFTER Trigger Job
The Trigger Plot Graph
INVENTED HERE!


A Trigger Plot is a computerized graph of trigger movement vs trigger force.

In the past judging a good trigger 'feel' has been really subjective.

When we do a "Trigger Job" you can SEE the improvement as well as feel it.


Goals of a FIRST Gunsmithing Trigger Job

  1. Smooth and eliminate grittiness in trigger feel. Improves predictability of release.
  2. Reduce trigger break force. Desirable release forces are for Self Defense: 10-12 lbs, for Plinking: 6-8 lbs, for Target or long range Hunting: 3-5 lbs.
  3. Reduce overall pull distance, “pre-travel,” to the extent that a reliable trigger reset will permit. Improves repeatability of shot placement.
  4. Reduce “over-travel” improves accuracy. If finger accelerates after pull and hits back stop too hard, it may jar the gun while the bullet is still in the barrel.
  5. Increase slope of trigger break force onset. Increases awareness of trigger brake point and repeatability of release and accuracy.
The Trigger Plot Graph 2

To the left is an actual Double Action Trigger Plot on a Ruger GP-100 revolver.


Trigger break force reduced from  10.87 pounds to  6.77 pounds. 


You can tell by the smoother blue line that the trigger feels smoother than before too.

 

Below is an actual Single Action Trigger plot from a Century 308 rifle.


Trigger break force reduced from  10.68 pounds to  5.84.
Trigger Pull distance shortened up by 30%.


At the top of the red graph line, you can see a "false break" peak. Our trigger job has smoothed that away, making a cleaner break.

    "Jed was absolutely terrific to work with."

    "Provided fair estimates and over-delivered on my expectations. I came in with the intractable problem of a stripped hex-head due using red Loctite [I should have used blue]. Jed repaired the problem with thoughtful precision. Highly recommended."
