A round that chambers on the press can still fail in the gun. Confirm fit before it becomes a problem at the line.

A gauge cut to SAAMI minimum chamber dimensions.

Chamber Check: Drop the round in the gauge. If it fits here, you have a fast read on whether it will fit a minimum chamber.

Machined Aluminum: Cut from solid 6061 T6 aircraft grade aluminum. Custom tooling holds the SAAMI minimum.

Pistol Coverage: This pistol and revolver checker covers 380 Auto, 38 Super, 38/357, 40 S&W, 44 Mag/Spl, 45 ACP, and 45 Colt.

One Gauge: One tool works across those common handgun calibers. You are not buying a block for every cartridge.

Bench Habit: You size, seat, and check. The round either drops or it does not.

Check the round before it ever sees a chamber.
