Measuring Pull Weight and Creep: Putting Numbers to How a Trigger Feels

A trigger can be described in words for only so long before someone asks for the number, and the number is easy to get. A gauge, a bench, a cleared rifle and ten minutes give a pull weight to the ounce, and a couple of simple tricks give creep, over-travel and reset as well. This guide explains how to take each measurement, what the results should be for different rifles, how to read a two-stage trigger, and what to expect as a trigger wears in.

Gauges

A mechanical spring gauge costs little and reads to a quarter pound; a digital gauge reads to the hundredth and records peaks. Either works. Both hook over the trigger and are pulled straight back along the bore line until the sear releases, and both need to be placed at the same point on the trigger shoe each time, because the trigger is a lever and the weight reads lower toward the bottom of the shoe. The convention is the centre of the shoe, or the point where your finger actually rests if you are measuring for yourself.

Measuring pull weight

Clear the rifle, remove the magazine, and confirm the chamber is empty. Cock the action. Hook the gauge at the chosen point, pull slowly and smoothly straight back, and read the peak when the striker or hammer falls. Take five readings and average them; note the spread as well. A good match trigger will vary by an ounce or two across five pulls, a good duty trigger by a quarter pound, and a factory mil-spec AR trigger by as much as a pound, which is why the spread matters as much as the average.

Reading a two-stage

A two-stage trigger gives two numbers. Pull slowly and watch the gauge: it will rise through the first stage, plateau or drop slightly at the wall, and rise again to the break. The first reading is the first-stage weight, the peak is the total, and the second-stage weight is the difference. A digital gauge with a peak-hold function makes this easy; with a mechanical gauge, note the reading at the wall by feel, then the peak. Service-rifle rules test the total with a hung weight, so the total is the number that matters for competition.

Measuring creep

Creep is movement under load before the break, and it is measured by feel and by eye rather than by gauge. Rest the rifle, put a strip of tape on the receiver behind the trigger, mark the trigger's position at rest, then take up the trigger to the point of full pressure just before release and mark again. Any visible movement between the marks on a single-stage trigger is creep. On a two-stage, measure from the wall, not from rest. A good match trigger shows none; a mil-spec trigger may show a millimetre or more.

Over-travel and reset

Over-travel is the movement after the break; mark the trigger's position at the instant of release and at the stop. Adjustable triggers let you set it close to nothing; leave a little on a defensive rifle so that a cold, dirty trigger still releases. Reset is measured by holding the trigger back after the break, cycling the action, and releasing the trigger slowly until the click; the distance moved is the reset. Short is good for fast shooting and irrelevant for precision.

What the numbers should be

• Benchrest and F-Class: ounces, single-stage, no creep.
• PRS and precision: one to two and a half pounds, spread under two ounces, no creep.
• Service rifle: four and a half pounds total or more, two-stage, tested at the match.
• Hunting bolt rifle: two and a half to three and a half pounds, no creep, full-power spring.
• Defensive and duty carbine: four and a half to five and a half pounds, spread under half a pound, a little over-travel.

Break-in

New triggers settle. The sear surfaces polish each other over the first few hundred cycles, and the weight typically drops a few ounces and the spread narrows. Measure a new trigger when it is fitted, again after two hundred rounds or a thousand dry presses, and again after a season, and keep the numbers; a trigger that keeps getting lighter is one whose engagement is wearing, and it should be inspected. Adjustable triggers should be re-checked and their screws re-locked after break-in.

The function check that goes with the numbers

A light trigger is only acceptable if the rifle passes its safety checks: safety on and trigger pressed hard, bolt or carrier closed briskly ten times, butt dropped onto a padded floor, none of which may release the striker or hammer. Do the checks every time the trigger is adjusted or a new one is fitted; the bolt-action guide and the maker's instructions set them out.

Measuring a rimfire and a pistol

The same gauge measures a rimfire rifle or a pistol. Rimfire target rifles run from a few ounces to two pounds and their spread should be as tight as a centerfire match rifle's; a 10/22 with a replacement group typically reads two and a half to three pounds. Pistol triggers are measured at the centre of the face with the gauge pulled along the bore line, and a defensive pistol should read between four and six pounds; below that, the same policy logic that applies to duty rifles applies. Log them all; a pistol's trigger drifts as much as a rifle's.

Temperature and lubricant

A trigger reads differently cold. Heavy grease on sear surfaces thickens below freezing and can add a pound or stop a light trigger releasing at all, which is why precision shooters lubricate triggers with a dry film or nothing. Measure a hunting rifle's trigger after an hour outdoors in November if you can; the number that matters is the one in the field, not the one on the bench in a warm room.

Keeping a log

Precision shooters log ammunition and zero; log the trigger too. Date, gauge reading, spread, creep and over-travel, and the setting of any adjustment screws. Six months later, when something feels different, the log tells you whether it is the trigger or the shooter.
