Mag Mpa 9mm Polymer 30rd Blk

The MasterPiece Arms Mag MPA 9mm Polymer 30-Round Black magazine is a purpose-built feed system engineered to meet the exacting standards of MasterPiece Arms pistol platforms. Built in polymer construction, this 30-round capacity magazine delivers reliable ammunition feed across training cycles, duty use, and defensive applications where high-capacity optics-compatible magazines are essential. Designed specifically for MPA 9mm pistols with serial numbers beginning with B or F (such as B1234 or F5678), this magazine ensures proper fitment and function without modification.

The polymer construction provides weight savings compared to steel alternatives—at 0.31 lbs per magazine—while maintaining dimensional consistency across mag changes. The 30-round capacity addresses shooters who prioritize magazine capacity without significantly impacting concealability or handling characteristics. At 10.25 inches in length and 2 inches in width, the magazine profile remains compatible with standard holstering and storage solutions. Polymer magazines require consistent cleaning and maintenance, particularly when running high-round-count training sessions or in duty environments where sand or debris ingestion can occur.

This magazine serves operators, competitive shooters, and defensive users who rely on MasterPiece Arms platforms and require reliable, manufacturer-specified ammunition storage. Those running legacy MPA pistols marked with B or F serial prefixes will find this magazine essential for maintaining rifle-rate-of-fire capability during extended range work or multi-stage shooting events. Law enforcement and armed citizens using MPA duty or carry platforms benefit from the 30-round capacity for qualified force scenarios requiring sustained firepower.

MasterPiece Arms magazines are manufactured to tight tolerances and material specifications that ensure zero-issue feeding across all environmental conditions and ammunition types. Buying from a verified manufacturer rather than third-party alternatives guarantees compatibility and eliminates fitment guesswork.
