SPEED BEEZ® Multi Pocket 40 S&W Chamber Gauge

Streamline Your Reloading with the .40 S&W Chambermaid Gauge

For competitive shooters and reloading enthusiasts, the SPEED BEEZ® Multi Pocket 40 S&W Chamber Gauge—nicknamed the “Chambermaid”—is your new best friend at the range. Instead of checking one round at a time, this high-performance tool lets you inspect 19 rounds of .40 S&W ammo in a single pass. Whether you’re prepping for competition or just ensuring smooth feeding, this gauge helps you detect improperly sized brass before it causes a malfunction.

Each of the 19 chambers is precisely reamed using an actual .40 S&W chamber reamer, making this gauge an indispensable tool for accuracy and confidence. Built from lightweight hard-anodized aluminum, it’s strong enough for range bags and daily use—yet compact enough to go anywhere.
