Key features that matter on the range and in the field

The FN 509 in this listing is optic-ready and comes equipped with optic-height night sights, making sight acquisition fast in low light and compatible with modern red dot footprints. The slide cut and included optic plates simplify mounting a miniature reflex sight without gunsmithing. The threaded barrel with thread protector allows quick attachment of muzzle devices or a suppressor adapter, expanding the pistol’s utility for range work and tactical setups.

Controls and ergonomics

This pistol includes an ambidextrous mag release and an ambidextrous slide lock/release, so left- and right-handed shooters get consistent, intuitive manipulation. The included backstrap lets you fine-tune the grip for positive purchase and better trigger control. FN’s ergonomic layout supports fast follow-up shots and reliable reloads under stress.

What’s included and why Certified Used is a strong value

Certified Used designation means the firearm is held to high quality standards and arrives in very good to excellent condition with a ‘no questions asked’ return policy—an important confidence factor when purchasing pre-owned firearms.
