Sig Sauer MPX 9mm Luger 20-Round Black Polymer Magazine

The Sig Sauer MPX factory 9mm Luger magazine delivers a true 20-round capacity in the standard pattern used across the entire Sig MPX pistol-caliber carbine line. Built around a lightweight black polymer body with reinforced metal feed lips for long-term durability, this OEM magazine is designed to drop in and feed reliably on every generation of the MPX.

Sig Sauer's MPX was engineered as a 9mm carbine that handles and controls like an AR-15, and the factory 20-round magazine reflects the same duty-grade intent. The polymer shell keeps carry weight down, while the metal feed lips and internal geometry preserve the precise feed angle required for fast cycling in 9mm Luger. Genuine Sig Sauer part number 8900828, this magazine is the correct factory replacement for MPX pistols, SBR configurations, and full-length carbines, and is a sound spare for range, training, and defensive use on the platform.
