Certified Used: What that stamp means for you

The Certified Used stamp verifies that this FN 509 has been inspected to a high standard and falls into a very good to excellent condition bracket. Certified Used firearms on our site include a ‘no questions asked’ return policy, which reduces buyer risk if the purchase doesn’t meet expectations. At $479.99, this package — complete with original box and owner’s manual — represents clear value for buyers prioritizing condition and documented provenance.

Features that matter in the field

Luminescent sights for low-light scenarios

Luminescent sights increase target acquisition speed in reduced light without batteries. For home defense or night-time duties, reliable sighting is a critical upgrade over standard iron sights.

Ergonomics and reload readiness

The included extra backstrap allows shooters to fine-tune grip fit for control and recoil management, while two 15-round magazines provide immediate reload capacity and reduce downtime during training or defensive drills. These practical accessories elevate the out-of-box utility.
