B&T GHM9 30-Round Magazine

The B&T factory 30-round magazine is the OEM feeding device for the GHM9 compact carbine and its siblings in the B&T lineup, including the APC9 and TP9. The translucent polymer body is a deliberate B&T design choice: operators can read remaining rounds at a glance without any round-count markings or removing the magazine. At just 2.9 oz empty, it is among the lightest factory 30-round 9mm magazines on the market.

The B&T magazine well is a proprietary design that does not accept Glock or other standard 9mm magazine patterns, making these factory magazines the primary and essentially only aftermarket-compatible option. Some third-party manufacturers produce B&T-pattern magazines, but factory B&T units are the compatibility benchmark. The rubber bumper pad on equipped versions absorbs drop impact and protects the polymer baseplate.

Note that the bumper pad is sold separately on some variants. Users report high reliability across all standard 9mm loadings, consistent with B&T's professional-grade build quality throughout the GHM9 platform.
