When evaluating a certified used handgun for home defense or duty carry, a clear-eyed assessment of condition, accessories, and return policy matters as much as the baseline platform. Experienced shooters want a package that’s ready to run out of the box, and certified used inventory can deliver significant value without sacrificing reliability.

FN 509 is offered here as a Certified Used Semi Auto that comes complete with a soft case, manual, one 15-round magazine, one 24-round extended magazine, a backstrap, and optic hardware. The Certified Used stamp guarantees the firearm is in very good to excellent condition and is backed by a ‘no questions asked’ return policy—an important safeguard when purchasing pre-owned.

Included accessories and practical impact

Magazines and ready-to-shoot capability

The combination of a 15-round standard magazine and a 24-round extended magazine gives immediate flexibility for range sessions, training drills, or defensive preparedness. Having both on hand reduces the need for immediate aftermarket purchases and lets you test concealment and holster fit with different capacities.

Optic-ready hardware and ergonomics

Optic hardware included in the package removes a common barrier to modern red-dot use—no milling or additional plates required. The backstrap allows straightforward grip personalization to improve sight alignment and recoil control. The soft case and manual complete the package so the pistol is transportable and documented out of the gate.

Price is set at $849.99 for this Certified Used offering in the Semi Auto category, which positions it as a value alternative to new inventory while keeping quality controls in place. For purchasing and verification, View product details and pricing.

Buying considerations for the tactical buyer

Confirm the Certified Used stamp and the included inventory—soft case, manual, magazines, backstrap, and optic hardware—before completing a purchase. The ‘no questions asked’ return policy reduces risk, so inspect fit, function, and optics fitment immediately upon receipt.
