FN 6647820 FNS12rd 9mm Luger FN FNS Compact Black Electroless Nickel Steel

The FN FNS Compact 9mm 12-round magazine is a factory OEM mag built to the same reliability standards as the pistol itself. If you run an FN FNS Compact for concealed carry, duty, or range work, having a spare magazine—or a couple—isn't optional. FN's compact mag pairs the proven feeding geometry of the FNS platform with a durable electroless nickel finish that resists corrosion and wear without the slickness that can cause reliability headaches. This is straightforward, no-nonsense magazine design: it works, it lasts, and it fits your gun the way the maker intended.

The 12-round capacity keeps the mag flush or nearly flush with the grip of your compact frame, so you're not adding bulk for concealed carry but still getting a reasonable round count for self-defense or range sessions. The flat polymer base pad is practical—it won't snag in a holster, and it's durable enough for years of practice and handling. The low-friction follower helps rounds feed smoothly under pressure, which matters when reliability counts.

OEM magazines are always the smart choice if you own the gun. They're engineered to your pistol's feed ramps and tolerances, tested to the same spec, and backed by the factory's reputation. Keep one loaded, keep spares staged, and you'll have one less variable to worry about.

Frequently Asked Questions

Will this magazine work with my FN FNS Compact?

Yes. This is the factory OEM magazine for the FN FNS Compact 9mm. It's engineered to the exact tolerances and feed geometry of your pistol.

What's the difference between the electroless nickel finish and regular blued steel?

Electroless nickel is a coating applied chemically and is more corrosion-resistant than traditional bluing. It also provides a lower-friction surface that can improve feeding and reduce wear on internal components over time.

Is 12 rounds enough for concealed carry?

That's a personal choice based on your threat assessment and comfort level. The 12-round capacity gives you a reasonable self-defense load while keeping the magazine compact—flush or nearly flush with the grip—which aids concealment. Many carry shooters keep a spare mag on their belt or in a pocket for additional firepower if needed.
