FN 509 Tactical 9mm Pistol 10+1 4.5" Threaded Barrel Optic Ready

The FN 509 Tactical delivers enhanced versatility for suppressor use and red dot optics in a striker-fired platform. This tactical variant features a factory-threaded barrel and optic-ready slide configuration that eliminates aftermarket modifications.

What Makes This Different

Unlike standard pistols requiring gunsmith services for suppressor mounting, the FN 509 Tactical ships with a factory-threaded 4.5-inch barrel ready for direct attachment of suppressors or muzzle devices. The optic-ready slide accepts popular red dot sights without adapter plates, while the extended slide serrations provide enhanced grip surface in adverse conditions. FN's cold hammer-forged barrel construction delivers consistent accuracy across extended firing sessions.

Key Features

• Factory-threaded 4.5" barrel with 1/2x28 thread pitch for suppressors
• Optic-ready slide cut compatible with major red dot sight brands
• Stainless steel slide with matte black finish and aggressive serrations
• MIL-STD-1913 Picatinny rail for tactical light/laser attachment
• Interchangeable backstrap system for custom grip fit
• Low-profile, snag-free three-dot sights
• Ambidextrous slide stop and magazine release controls

The 509 Tactical performs consistently across duty and competition applications. The 4.5-inch barrel length provides increased velocity and sight radius compared to compact models, while maintaining manageable overall dimensions. Weather-resistant polymer frame construction withstands temperature extremes and moisture exposure. The striker-fired action delivers consistent trigger pull characteristics shot after shot.
