FN 509 Midsize 9mm Luger 15-Rd Black Stainless Steel Pistol Magazine

The FN 509 Midsize pistol pairs a compact slide and grip with duty-grade shootability, and this factory 15-round magazine is the standard companion for keeping it fed and ready. Built specifically for the Midsize variant, it delivers the same dependable cycling the FN 509 lineup is known for in a magazine tailored to that frame size.

The body is polished stainless steel, finished in black for corrosion resistance and a clean look that matches the factory slide. An orange polymer follower and black polymer buttplate round out the magazine, providing smooth, consistent feeding of 9mm Luger ammunition round after round.

Engineered exclusively for the FN 509 Midsize pistol, this 15-round detachable magazine is the correct OEM replacement for the standard-capacity magazines that ship with the firearm. It is also an ideal spare or backup for range sessions, duty carry, or home-defense use, giving you extra rounds on hand without compromising fit or function.
