For shooters focused on reliable performance for both defensive carry and range training, a handgun with proven service-grade design and practical accessories is essential. The FN 509 delivers a solid blend of duty-level engineering and everyday practicality that suits new owners and experienced operators alike.
FN 509 
Design & heritage
Built from a platform originally developed for military and law enforcement use, the FN 509 reflects the durability and ergonomics expected of a duty pistol. The design was submitted to the U.S. Army handgun trials — ultimately bested by the Sig P320 (M17) — but its lineage shows in the robust controls, textured grip, and modular backstrap system that improves fit for a wide range of shooters.

What’s included and value
This Certified Used FN 509 package includes one 15-round magazine, one 12-round magazine, the original box, manual, and an extra backstrap. Certified Used status means the firearm is inspected and rated very good to excellent, and it carries a ‘no questions asked’ return policy to give buyers confidence at a price point of $522.49. That combination of included mags and documented condition makes this a practical buy for someone wanting immediate range-ready capability without chasing parts.
Range performance and defensive application
On the range the FN 509’s duty-oriented controls and sighting platform make rapid follow-up shots and transitions straightforward. While the specific caliber isn’t listed on this Certified Used listing, the platform is commonly available in standard defensive calibers; pairing the right ammunition choice with the ergonomics and included magazines will suit personal defense or frequent training sessions. The modular backstrap helps tailor recoil management and sight alignment for faster, more consistent accuracy.
