Description
This factory FN 509 Compact magazine is the OEM detachable spare built specifically for the 509 Compact pistol. It ships with an installed grip sleeve so the compact-frame magazine seats flush in the grip of a midsize or full-size 9mm Luger 509 pistol, giving the shooter a full-hand purchase on a longer frame.
Constructed around a steel body with a low-glare black finish, this OEM magazine uses a steel wire internal spring and a high-visibility anti-tilt polymer follower to keep rounds stacked properly for reliable feeding. An extended polymer floorplate makes the magazine easier to seat and draw from a pouch, while the included grip sleeve simply snaps on over the baseplate to bridge the compact magazine to a larger 509 frame.
Designed for the FN 509 Compact, this 15-round factory spare delivers the duty-grade reliability of the original offering for your CCW or service pistol.
