FN Flat Stainless Steel 9mm Luger Fits 509 High Visibility Follower

The FN 509 17-round 9mm Luger magazine from FN combines a polished stainless steel body with a flat black finish, high-visibility anti-tilt follower and a flat base pad to give 509 owners reliable feeding, positive handling and a clean aesthetic that matches factory pistols. Designed as a detachable handgun magazine that fits the FN 509 model, this 17-capacity stainless steel magazine handles standard 9mm Luger loads with smooth index and spring tension, while the anti-tilt follower reduces binding for faster reloads and improved range drills. The durable flat finish resists wear from holstering and racking, and the flat base pad provides a stable grip surface for controlled reloads under stress or in competition. Whether used for range practice, carry rotation, or match shooting, this magazine integrates seamlessly with FN 509 pistols to extend capacity and maintain consistent, dependable performance.
