Fn 509m Tactical 9mm 4.5 inch 15+1 and 24 round Optic Ready Matte

The FN 509 Tactical builds on the FN 509 family and the Army's Modular Handgun Trials submission to deliver a duty-grade 9mm Luger semi-auto pistol that works for range days, competition stages, or duty carry, and requires FFL transfer. This striker-fire handgun wears a matte black frame with black interchangeable backstraps for tailored ergonomics, a 4.50" cold hammer-forged stainless barrel with a target crown and 1/2"-28 threads for mounting most 9mm suppressors plus a thread cap with O-ring to prevent loosening, and an optic-ready, serrated slide fitted with a Holosun red dot and a slide cap with raised sight wings to protect the 3-dot night/suppressor-height iron sights when running iron co-witness or stowed. The 15+1 capacity standard configuration and extended 24-round magazines keep you shooting longer without changing how the pistol carries, while the textured slide ramp aids press checks and racking against a belt or boot. With FN's reputation for reliability, this semi-auto handgun brings practical tactical features—optic readiness, suppressor compatibility, rugged barrel and night sights—that make it suitable for defensive use, suppressed shooting, and competitive service-pistol work.
