FN 509 9mm 24-Round Magazine Kit - Black

The FN 509 9mm 24-Round Magazine Kit is a factory original extended-capacity replacement magazine built for the FN 509 family of 9mm Luger striker-fired pistols. Constructed on a stainless steel body with a corrosion-resistant black finish, this 24-round magazine is the same unit FN America ships with select FN 509 packages and serves as a genuine OEM replacement for any FN 509 variant in the rotation.

Unlike most pistol magazines, the FN 509 24-round kit ships complete with all three grip extension floorplates in the box, allowing the same magazine body to be tailored on the fly for the FN 509 Compact, Midsize, or Full Size slide lengths. Switching the base plate swaps the magazine's footprint to match the host pistol's grip frame, so a Compact owner gets a flush-fitting spare while a Full Size carrier can run it flush or extended without buying a second magazine.

Chambered in 9mm Luger, the steel-bodied magazine is built to the same factory tolerances as the equipment originally delivered with the pistol, so reliability carries over directly from the gun to the spare. The blacked surface treatment resists sweat, holster wear, and the kind of corrosion that works its way into a magazine during daily carry.

This listing is for one (1) FN 509 9mm 24-Round magazine in black, factory packaged with the full set of Compact, Midsize, and Full Size grip extension base plates.
