| Introduction:
Most folks will agree that they would
prefer that their Glock's trigger be a little more "user
friendly", especially for competition. This article will track my
Glock 22 trigger system's (hopeful) improvement as I proceed through a
list of modifications. Use the article index above to jump to the pull
weight table to check for updates if you've been here before.
At Right: This is an image of the
very simple setup that I will be using to measure the trigger pull
weight. Essentially, the pistol is set in a bench mounted vice with the
slide vertical. A simple harness is rigged over the trigger and a bag is
hooked to the harness. Weight is added to the bag in the form of 40
S&W cases which yields an incremental weight increase of
approximately +/-4.5 g per case.
I submit that this method is quite a bit
more accurate than any currently marketed trigger scale for several
reasons:
- it has no springs or moving parts,
- it is a static system and not nearly
as prone to errors due to differing static and kinetic coefficients
of friction, and
- it is accurate to within approximately
0.1 grams vs. 2 oz. (56.75 g) or more for the average trigger scale.
