FN America FN509M 9mm

The FN 509M Tactical is a midsize, red-dot-ready 9mm pistol intended for duty, everyday carry, home defense, and range use. It pairs a full-featured slide with a midsize frame to balance controllability and capacity for training and operational roles. The included Holosun 407C sight and a threaded barrel expand its versatility for users who mount optics or accessories.

The pistol is built on a polymer frame with enhanced grip texturing and interchangeable backstraps to tailor ergonomics to the shooter. The top end uses a cold hammer-forged stainless steel barrel with a recessed target crown and 1/2×28 threads; the slide is optic-ready and features front and rear cocking serrations and suppressor-height 3-dot sights. Controls are fully ambidextrous where noted, and the package includes two magazines and a case.
