Design and construction

This 15-round, 9mm Luger magazine is purpose-built for the 509 Midsize series of pistols manufactured by FN Herstal. The polished stainless steel body with a flat black finish combines corrosion resistance with a subdued appearance suitable for duty or carry. High-visibility anti-tilt followers are integrated to reduce binding and follower tilt, improving reliability during rapid reloads and high-round-count sessions.

Why the 9mm Luger matters here

The 9mm Luger is the industry standard for many law enforcement and civilian defensive platforms thanks to its balance of capacity, controllable recoil, and broad ammo availability. A 15-round capacity in a midsize package gives an optimal mix of hold capacity and grip ergonomics for most shooters, making this magazine a good match for defensive use, training, and competition practice.

Field performance and handling

Anti-tilt followers and the polished stainless body work together to ensure smooth feeding from single-stack transitions to full reloads. In practical terms, that means fewer stovepipes and more consistent function under stress or in rapid-fire drills. The flat black finish reduces glare while remaining tough against everyday wear.

Practical purchase considerations

At $49.99, this magazine sits in a competitive price band for OEM-style magazines. For owners of the FN 509 Midsize platform who want OEM compatibility, robust materials, and a high-visibility follower for reliability, it’s a straightforward value proposition. Carry or storage practices should include regular inspection and function checks to maintain peak performance.
