The ProMag FNH Five Seven Magazine IOM & USG Black Polymer 5.7x28mm 30/rd provides a high-capacity solution for operators utilizing the FNH Five-seveN platform in professional or defensive environments. Specifically engineered for compatibility with both the Individual Officer Model (IOM) and United States Government (USG) variants, this extended magazine increases the standard capacity to 30 rounds, offering a substantial advantage in sustained fire scenarios. This magazine is designed to meet the rigorous demands of duty use where reliability and volume are paramount.
Constructed from impact-resistant glass-filled nylon polymer, the housing and follower are built to withstand the physical stresses of rapid reloads and varied environmental conditions. In the field, gear must survive drops and temperature fluctuations without compromising structural integrity. The injection-molded housing ensures consistent dimensions for smooth insertion and extraction from the mag well, while the follower provides a stable platform for the 5.7x28mm cartridge to cycle reliably into the chamber.
Internal performance is driven by a precision-wound spring manufactured from heat-treated chrome-silicon wire. For professionals who keep magazines loaded for extended periods, the choice of chrome-silicon is critical as it resists fatigue better than standard carbon steel, maintaining the necessary upward pressure for consistent feeding through the final round. This focus on internal metallurgy ensures that the ProMag FNH Five Seven Magazine IOM & USG Black Polymer 5.7x28mm 30/rd performs predictably under high-cadence fire.
Whether you are refining your skills on the range or seeking to maximize your loadout capacity, this 30-round magazine offers a durable alternative to standard factory options. By integrating advanced polymers with proven spring technology, ProMag delivers a specialized component that supports the unique ballistics and high-velocity requirements of the 5.7x28mm cartridge.
