Overview
The ProMag FNHA13 magazine is purpose-built to integrate seamlessly with the FN 509 pistol platform, providing an extended 20-round capacity for operational flexibility. This unit delivers consistent ammunition feeding, engineered for reliability in demanding applications.
Key Features
Capacity & Compatibility
This magazine offers a 20-round capacity for 9mm Luger ammunition, specifically designed for direct compatibility with the FN 509 series of pistols. This extended capacity facilitates reduced reload cycles, optimizing operational tempo for both training and duty use.
Construction & Durability
The magazine body is constructed from heat-treated blued steel, a material selected for its structural integrity and resistance to wear and corrosion. A proprietary anti-fatigue spring ensures consistent tension and reliable cartridge presentation over an extended service life. The injection-molded polymer follower is designed for smooth, low-friction interaction with the magazine body and ammunition stack, mitigating potential for feeding anomalies.
Reliability & Feeding
Precision manufacturing processes ensure critical internal dimensions are maintained, promoting consistent cartridge alignment and reliable feeding into the chamber. The blued finish contributes to both corrosion resistance and a low-friction internal environment, crucial for mitigating operational stoppages.
