The Lyman Pistol Maximum Cartridge Gauge for 9mm (Lyman part no. 7832330) lets handloaders verify that finished cases fall within proper dimensional limits before they ever get loaded into a magazine. Lyman builds these gauges in a range of calibers to match the most popular case dimensions, and checking a case against one helps ensure reliable ignition, more consistent accuracy, and an added margin of safety during reloading. An out-of-spec case can cause feeding or chambering problems downstream, and this gauge catches that before the round is finished. At 4.35 inches overall, it’s a compact bench tool worth keeping within reach on every 9mm loading session.
