The Firearm Trigger Scale allows you to check the pull weight of your firearm trigger yourself. Compatible with pistols, revolvers, rifles, and shotguns. This tool checks the trigger pull weight in quarter pound increments from 0 to 11 pounds, allowing you to determine how much you want to adjust your firearm’s trigger pull weight. The Firearm Trigger Scale has an anodized aluminum body with a curved stainless steel trigger pull. The handle is rubber dipped to prevent scratching your firearms and can be configured for right or left handed users. The Firearm Trigger Scale will give you an accurate reading of the trigger pull weight of your firearms without needing to visit a gunsmith.
