L.E. Wilson Case Length Gauge 9mm Luger

The L.E. Wilson Case Length Gauge for 9mm Luger is a precision one-piece, non-adjustable cylinder-type gauge designed to check the minimum and maximum overall length of straight-walled pistol cases. Milled surfaces on one end allow for easy measurement — simply set the case on a flat surface, slide the gauge over the top (grooves up), and run a straight edge across. Note: this gauge does not measure body diameters; use the Pistol Max Gauge or Min Dimension Gauge for that purpose. Made in the U.S.A.
