Lyman's mechanical trigger pull gauge is a simple, precise, and cost-effective way to measure your firearm's trigger pull. Constructed of durable machined aluminum and steel components, the gauge will withstand years of use.

The device features a rolling trigger shoe, a "T" handle, a sliding indicator that holds your heaviest weight, and a zero position adjustment dial.

The gauge displays weights from 0 to 12 pounds in 2-ounce increments and also features a hanging loop for storage.
