Lyman Electronic Digital Trigger Pull Gauge

The Lyman Electronic Digital Trigger Pull Gauge is a precision tool used to measure the force required to pull a firearm’s trigger. Designed for accuracy and ease of use, this digital gauge provides clear weight readings in either ounces/pounds or grams/kilograms, helping shooters, gunsmiths, and hunters verify and fine‑tune trigger pull weights on rifles, pistols, and shotguns.

Key Features

Digital Readout with Large LCD

• Easy‑to‑read display shows trigger pull weight clearly, eliminating guesswork associated with traditional spring‑type gauges.

Accurate Strain Gauge Technology

• Uses an electronic strain sensor for precise measurements to within approximately 0.1 oz (2 g), making readings reliable across multiple firearms.

Wide Measuring Range

• Can measure pull weights from about 1 oz up to 12 lb (2.8 g to 5.4 kg), suitable for most triggers from light competition setups to heavier factory triggers.

Adjustable Pull Rod

• Telescoping or adjustable trigger pull rod lets you position the gauge correctly on many different firearm trigger types and align for smooth pulls.

Memory & Averaging

• Stores recent readings and can calculate an average of up to ~10 pulls, helping you identify consistent pull weight trends.

Switchable Units

• Allows toggling between imperial (oz/lbs) and metric (g/kg) readouts with a simple button press.

Wide Compatibility

• Works with most handguns, rifles, and shotguns — across a broad range of trigger geometries — making it a versatile workshop tool.

Technical Specifications

(Measurement precision varies at higher weights; gauge stores and averages multiple pulls.)

Performance & Practical Use

The Lyman Electronic Digital Trigger Pull Gauge helps you measure and compare trigger pull weights quickly and with greater precision than basic mechanical pull gauges. By attaching the adjustable trigger rod and positioning its roller on your firearm’s trigger, you pull back until the trigger releases. The gauge instantly displays the pull force and holds the value for review. This electronic method improves repeatability and reduces guessing inherent to spring scales, which is especially useful when fine‑tuning triggers for competition, hunting, or personal preference.

The ability to switch between measurement units makes it usable in workshops that operate in either imperial or metric systems. Its memory function also helps you track consistency across multiple tests. Regular use after adjustments or gunsmith work ensures your trigger settings are exactly where you want them for safe and effective function.

Best Suited For:

✔ Checking and validating trigger pull weights
✔ Gunsmiths, target shooters, and competitive shooters
✔ Firearm hobbyists who make trigger adjustments
✔ Hunters who fine‑tune trigger feel before the season

User Tips

Always Ensure Firearm Is Unloaded:
Before using this gauge, make sure the firearm is completely unloaded and pointed in a safe direction.

Use Consistent Pull Technique:
For repeatable results, try to pull the trigger slowly and straight back — jerky or angled pulls can skew readings.

Average Multiple Reads:
Take a set of pulls and use the gauge’s averaging feature to find a reliable average rather than trusting a single read.

Store Safely:
Remove batteries if the gauge won’t be used for extended periods to prevent corrosion.
