Masterpiece Arms Handgun & Rifle Magazine 9mm 30/rd

The MasterPiece Arms Handgun & Rifle Magazine 9mm 30-round capacity polymer magazine (MPA20-70P) is a high-capacity polymer magazine engineered for MasterPiece Arms platforms. This 30-round 9mm magazine delivers reliable feed and extraction performance across both handgun and rifle configurations where MPA platforms are chambered in 9mm, offering shooters extended magazine capacity for range training, duty use, or competitive applications without frequent reloads.

Constructed from reinforced polymer, the magazine weighs just 0.29 lbs and features compact dimensions (3 x 1.25 x 12.25 inches) that facilitate fast magazine changes and reload transitions. The 30-round capacity makes this magazine suitable for high-volume training sessions where ammunition consumption demands extended firepower without breaking shooting rhythm. The polymer construction resists corrosion from environmental exposure and provides consistent dimensional stability across temperature variance—critical for magazines that see frequent cycling and storage in varied conditions.

This magazine is designed specifically for MasterPiece Arms firearms with serial numbers beginning with B or F designations. While intended as a primary magazine for MPA 9mm platforms, operators and shooters should verify compatibility with their exact firearm model before purchase. The 30-round capacity positions this magazine within the extended-magazine class, suitable for shooters who prioritize magazine-fed volume and reduced reload frequency over ultra-concealable profiles. Whether deployed for range days, training evolutions, or platform-specific duty use, this MPA 9mm magazine provides dependable feeding and straightforward reliability for MasterPiece Arms users.
