FN 509 Tactical 9mm 4.5" Threaded Barrel 10+1 FDE Frame

The FN 509 Tactical delivers enhanced suppressor compatibility and optic-ready versatility in a proven striker-fired platform. This tactical variant features a threaded barrel and factory optic cut, addressing the specific needs of shooters requiring NFA accessory compatibility and red dot integration.

What Makes This Different

Unlike standard pistols requiring aftermarket modifications, the 509 Tactical ships with factory threading and an optic-ready slide cut. The 4.5-inch threaded barrel accepts standard 1/2x28 suppressors and compensators without additional gunsmithing. FN's cold hammer-forged barrel construction provides consistent accuracy while the stainless steel slide offers superior corrosion resistance compared to standard carbon steel alternatives.

Key Features

• Factory threaded 4.5" cold hammer-forged barrel with 1/2x28 TPI threading
• Optic-ready slide cut accepts popular red dot sights including Trijicon RMR and Leupold DeltaPoint Pro
• Flat Dark Earth polymer frame with integrated Picatinny rail for tactical accessories
• Ambidextrous controls including slide stop and magazine release
• Low-profile night sights co-witness with mounted optics
• Enhanced trigger with approximately 5.5-7 lb pull weight
• Includes two 10-round magazines and thread protector cap

Range performance demonstrates consistent 2.5-3 MOA accuracy with quality ammunition, suitable for competitive shooting and tactical applications. The 509 Tactical functions reliably with both supersonic and subsonic loads when suppressed. Weather sealing protects internal components during adverse conditions, while the textured grip panels maintain control in wet environments.
