Lyman Case Length Headspace Gauge 9mm Luger

The Lyman 9mm Luger Case Length Headspace Gauge is a precision reloading tool that lets handloaders confirm both case length and headspace dimensions on spent 9mm Luger pistol brass in a single step. Simply drop each case into the gauge to verify that it is within specification limits before resizing and reloading - catching out-of-spec brass early helps maintain accuracy and safe chambering.

Constructed of rugged metal and sized to sit next to your press or case-prep station, this compact gauge measures approximately 1.40" H x 2.50" W x 4.35" L. It is part of Lyman's long-running family of case length and headspace gauges, here configured specifically for the straight-walled 9mm Luger pistol cartridge - a simple, durable bench tool that belongs in every 9mm reloading setup.
