FN 509 12rd Extended Floorplate 9mm Luger Pistol Magazine - Gray Aluminum Base Pad

The FN 509 12-Round Extended Floorplate Magazine is a factory 9mm Luger pistol magazine designed specifically for the FN 509 CC Edge compensator-equipped pistol. This drop-in magazine carries 12 rounds and features a distinctive gray aluminum extended floorplate that adds material below the magazine body for easier extraction and a more positive grip during fast reloads.

Built to FN's factory specifications, this extended floorplate is constructed from aluminum in a gray finish, providing a durable contact surface at the base of the magazine. The extended profile offers additional material below the magwell for confident, consistent magazine pulls, while the factory fit ensures reliable feeding in the FN 509 CC Edge. Whether you are supplementing a CC Edge loadout or replacing a worn magazine, this is the FN 12-round extended magazine built for that specific platform.
