FN 509 9mm

Updated August 24, 2026

This FN 509 semi-automatic pistol is chambered in 9mm and comes equipped with a threaded barrel and Crimson Trace red dot sight, making it an especially appealing modern handgun package. Serial number GKS0108606, this example features an approximately 4.5" barrel with a shiny bore and remains in good overall condition. The pistol utilizes a durable polymer frame with an aggressively textured synthetic grip paired with a steel slide and striker-fired operating system. The threaded barrel adds additional versatility, while the Crimson Trace optic provides a modern electronic sighting solution. No magazine is included. FN developed the 509 from its military handgun competition experience, and the platform quickly became one of the company’s flagship modern pistols. With its threaded barrel, quality red dot sight, full-size configuration, shiny bore, and respected FN pedigree, this example offers considerably more visual and practical appeal than a basic factory 509.
