If you run an FN Five-seveN, reliable magazines are non-negotiable—and that's where the ProMag Magazine FN Five-seveN 5.7x28mm polymer magazine comes in. Built with precision and durability in mind, this American-made magazine delivers the dependable feed reliability you need whether you're at the range, in competition, or relying on this capable platform for personal defense. The 20-round capacity gives you solid ammunition on board without excessive bulk, and the proven polymer construction stands up to hard use and storage.
ProMag has invested the engineering work where it counts: magazine springs are precision-wound from heat-treated chrome silicon wire to ensure consistent performance through thousands of cycles. Every step of assembly is inspected and verified to catch defects before they reach you, so you get the same quality in every magazine you buy. That's the difference between a magazine that works and one that works reliably, every time.
The black polymer body is tough and lightweight, resisting corrosion and abuse far better than metal alternatives. Whether you're stocking spares for your range bag, building a backup magazine battery, or just keeping a proven option on hand, this FN Five-seveN magazine offers genuine reliability backed by a lifetime manufacturer's defect guarantee.
