Shop this product to review the full listing and secure the certified example priced at $599.99. This listing lives in the Semi Auto category and represents an Fn-built platform offered as a Certified Used firearm — inspected to ensure condition ranges from very good to excellent and backed by a no-questions-asked return policy.

What’s included and why it matters

This FN 509C package contains the original box, a soft case (note: the zipper is broken), one 15-round magazine, and the optic hardware — though the front spacer for the original plate is missing. Those specifics are important for buyers: the included 15-round magazine gives you a ready-to-shoot baseline capacity, while the optic hardware indicates previous preparation for a red dot but may require a replacement spacer or alternative mounting solution for a perfect fit.

Tactical and practical considerations

Optic setup

Because the optic hardware is present but missing the front spacer, plan for a brief parts swap or use an aftermarket mounting plate. That small repair is less costly than purchasing a complete optic-ready slide, and it keeps the pistol lightweight and low-profile for duty or carry setups.

Carry and storage

The soft case shows wear (zipper broken), so budget for a durable case or holster if you’ll transport the gun regularly. The original box remains useful for storage and transfer paperwork, another plus when buying Certified Used.

Value and assurance

At $599.99, this Certified Used FN 509C offers strong value for shooters who want an Fn-built platform with documented included accessories. The Certified Used stamp confirms the firearm was inspected to retailer standards and includes the retailer’s return guarantee — a practical layer of consumer protection.
