Design and key features
The FN 509 emphasizes a full-size grip and sight radius for improved accuracy in rapid engagements. As a striker-fired pistol, it offers a consistent trigger pull cycle that many operators prefer for defensive shooting. The polymer frame keeps weight controlled while maintaining durability suitable for daily carry on duty or for conditioning at the range.
Sights and controls
Interchangeable night sights are a standout: they allow quick low-light target acquisition and the option to swap sight styles to match user preference or mission needs. Controls are intuitive and designed for a wide range of hand sizes, which helps reduce training time and improves follow-up shot speed.
Why 9MM works for defense
Chambered in 9MM, the FN 509 benefits from proven ballistics, manageable recoil, and common ammunition availability. For personal defense and professional use, 9MM balances capacity and terminal performance while keeping recoil low enough for rapid, accurate follow-up shots.

At $549.99, the FN 509 offers a competitive price point for a duty-ready, full-size platform that includes a single magazine and soft case—useful for secure transport and storage.
