Not too long ago I wanted to try my hand at a little gunsmithing and upgrade a trigger assembly to an aftermarket competition-grade trigger assembly. I wanted to test the trigger-pull at each step of the way so I could ensure the final result would be as expected. After going through dozens of forums, reviews and blogs, I decided to try Lyman’s Digital Trigger Pull Gauge for myself.
Lyman’s trigger-pull gauge arrives packed in a small zippered pouch that is padded for protection. Each component is strapped in with Velcro straps and there is a small pocket to store a 9v battery that is not supplied.
The trigger-pull gauge comes with an “L” shaped removable pull-rod with a roller on the end. The rod is about 5″ long with a 2-inch “finger” where the roller is attached and attaches to the gauge simply by threading it all the way into the end of the gauge and tightening the locking nut. Then twist the rod as necessary to set the direction of the finger.
Safety is king… Please make sure your firearm is not loaded and it is safe to test fire, whether that be with or without a hammer-block device or snap loads.
Once the rod is connected and the finger is facing the right direction and your firearm is cocked and safe to test fire, you are ready to test the trigger-pull. Position the roller on the trigger and align the gauge in a direction where you can pull in a smooth and consistent manner just until the trigger releases the hammer.
Whenever possible use a gun vise to secure the firearm. It will make things go much easier for you. Holding the firearm while pulling on the test gauge can be more than a little awkward, especially with a long rifle.
Additionally, on firearms with hinged triggers and trigger safeties, you must take care to properly set the roller and pull angle to obtain an accurate reading.
Learning to operate the trigger-pull gauge accurately takes a little patience and practice. I found that holding the gauge at 90˚, the rod and finger were best-aligned for consistent trigger-pulling. To get the most accurate reading out of your gauge, it is best to take at least 3 readings and as many as 10, then use the Average feature to display the combined results.
Although Lyman’s Digital Trigger-Pull Gauge is a little pricey at around $50, I found it invaluable for accurately testing (and averaging) my triggers.
The only negative I found is related to the roller itself. The small roller supplied with the unit does not always contact enough of the trigger’s surface to release the safety with some a hinged-trigger assemblies. Simply providing a larger roller with the unit would better accommodate the many trigger variations. I have seen user-modifications out there, but larger factory-supplied roller would be a better choice to solve this minor problem.
