ProMag FN Five-seveN Magazine – 5.7x28mm – 30 Rounds – Black – FNH-A2
The ProMag FNH-A2 is the definitive high-capacity extended magazine for the FN Five-seveN pistol, offering a massive 50% increase in firepower over standard 20-round factory mags. Designed for the 5.7x28mm enthusiast in 2026, this 30-round magazine is perfect for high-volume range sessions, competition shooters, and tactical trainers who value less time reloading and more time on target. While the Five-seveN is known for its impressive capacity, the FNH-A2 pushes the platform to its limits, turning your sidearm into a high-capacity defensive tool with the reliability that ProMag has refined over decades of manufacturing.
Built to handle the unique geometry of the 5.7x28mm cartridge, the magazine body is constructed from proprietary DuPont Zytel™ based polymer. This glass-reinforced nylon is legendary for its impact resistance, ensuring the magazine won't crack or swell even under hard use or extreme temperatures. Internally, the FNH-A2 features a heat-treated chrome silicone wire spring and an injection-molded follower, providing the consistent upward tension necessary for the Five-seveN’s high-speed cycling. The sleek black finish and molded grip sleeve ensure it looks like a natural extension of the pistol's frame. Backed by a Lifetime Warranty, it is one of the most popular aftermarket upgrades for the FN 5.7 platform.
Includes: (1) ProMag 30-Round 5.7x28mm Magazine for FN Five-seveN (Black).
