Smaller diameter heads let you see more of what you’re trying to hit, giving you better control. The lighter 4 oz. weight is our favorite for the bulk of most pistolsmithing work. Tough, long- lasting, non-marking extruded nylon and turned brass heads are easily replaced when they wear out or become deformed. Mfg: Brownells SPECS: 3/4" (19mm) diameter faces, 10 7/2" (26.67cm) long hickory handle, 4 oz. (113g) approximate weight.
