MAG B&T MP9/TP9/APC9/SPC9 9MM 20RD

Description

B&T designed this 20-round magazine as a factory-original feeding solution for their MP9, TP9, APC9, and SPC9 platforms. Because it comes from the same manufacturer as the firearms themselves, the feed geometry, spring rate, and follower profile are matched to those actions from the start rather than adapted after the fact. That matters most under rapid-fire strings, where a mismatched follower angle or a spring that is too light can cause the bolt to outrun the round presentation.

The body is constructed from impact-resistant polymer, which keeps weight low while giving the magazine enough flex to absorb the shock of hard reloads without cracking. An integrated rubber bumper at the base extends that protection to drops on hard surfaces during training, where magazines hit the deck frequently and unprotected bases tend to split at the seam. The bumper is part of the magazine’s molded geometry rather than a separate clip-on addition, so it does not come loose under field conditions.

At 20 rounds, this magazine sits between B&T’s 15-round and 25-round options for these platforms. The shorter stack height makes it easier to perform prone reloads and reduces the chance of the magazine contacting a rest or barricade while shooting. For shooters running the SPC9 or APC9 in competition or professional use, having a consistent factory magazine in rotation alongside higher-capacity options provides a reliable baseline for drills that require a consistent, known capacity.
