Built around an ergonomic plastic handle, the Wheeler® Trigger Pull Scale accurately measures the pull weight of your firearm trigger, allowing you to make precise adjustments to your trigger—without the need to visit a gunsmith. Compatible with pistols, revolvers, rifles, and shotguns, this trigger gauge measures pull weights from 8 oz. to 8 lbs., allowing you to determine how much you want to adjust your firearm’s trigger pull weight, and is compatible with both right- and left-handed users. Plus, this accurate trigger scale features highly visible increment markings and an easy-to-read sliding indicator that stays on the maximum weight registered to make it exceptionally easy to read.
