Digital Trigger Pull Gauge – 0 to 12 lb – LCD – Zippered Case
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Lyman Digital Trigger Pull Gauge is a gunsmithing and diagnostics tool built to measure trigger pull weight on rifles, shotguns, and handguns. It uses strain gauge technology, reads up to 12 pounds, and gives you a faster, more repeatable way to check trigger weight than old-school spring-style gauges. This is the kind of tool that helps you measure what your trigger is actually doing instead of guessing and calling it “about right.”
If you tune triggers, compare factory pulls, or want a before-and-after number when changing springs or components, this tool earns its spot on the bench. It stores high, low, average, and current readings, which matters when you are trying to see patterns instead of just one lucky pull.
Fitment
- Works with most rifles, shotguns, and handguns.
- Designed for measuring trigger pull weight, not for installation or adjustment by itself.
- Uses a roller-style hook interface to engage the trigger during measurement.
Does NOT fit
- Not a universal repair tool for fixing trigger problems by itself.
- Not a replacement for safe function checks, proper armorer work, or live-fire validation after modifications.
What it does
This tool measures trigger pull weight so you can quantify changes instead of eyeballing them. It helps you check factory trigger pulls, compare multiple guns, confirm the results of spring or connector changes, and document average pull weight over repeated readings.
Why it’s worth it
If you do any real trigger work, this keeps opinion out of the equation. It is useful for gunsmithing, competitive tuning, maintenance checks, and basic bench documentation. The digital readout, memory functions, and decent accuracy make it a practical shop tool instead of a gimmick.

Tools needed
No extra tools are required to use the gauge itself, but safe firearm handling, an unloaded firearm, and a clear work area are non-negotiable.
Install notes
This is a measurement tool, not an installed part. Always verify the firearm is unloaded before testing. For best results, take multiple pulls and use the average reading rather than hanging your hat on one number.
Verify before you buy
Verify you need a trigger pull measurement tool and not a trigger adjustment tool. This gauge measures pull weight; it does not change it. If you are doing post-install trigger work, proper safety checks and live-fire confirmation still matter.
