The FN 663302 FNS 17-round 9mm Luger magazine is the factory-standard magazine for FN's FNS-9 pistol platform. Built by FN America, this OEM magazine delivers the reliability and fit you'd expect from the manufacturer that engineered your gun. Whether you're stocking spares for daily carry, competition, or duty use, OEM magazines are the foundation of dependable feeding—no guesswork, no compatibility surprises.
The magazine bodies are stainless steel with a black finish, built to handle the wear and tear of regular loading, unloading, and hard carry. The polymer floorplate and follower round out a design that balances durability with shootability. A larger polymer floorplate gives you a solid grip surface when stripping the magazine from a retention holster or pouch—a small detail that matters when you need reliable magazine manipulation under pressure.
Round-count witness holes on the rear of the magazine let you do a quick visual on your remaining ammunition without removing it from the gun or pouch. No more guessing; just a glance to see where you stand. If you run an FNS-9 and want mags you can trust, FN's own factory magazines are the smart choice.
