FN 509 Compact Tactical 9mm w/ Viper Red Dot - Threaded Barrel

The FN 509 Compact Tactical delivers suppressor-ready capability in a duty-sized package that bridges the gap between concealed carry and full-size performance. This optics-ready pistol combines FN's military-proven reliability with enhanced features for tactical applications.

What Makes This Different

Unlike standard compact pistols, the 509 Compact Tactical features a factory-threaded barrel and comes equipped with a Viper red dot sight from the factory. The optic-cut slide eliminates the need for aftermarket modifications, while the extended 4.32-inch threaded barrel provides improved velocity and suppressor compatibility. The dual magazine capacity options offer flexibility between concealment (12+1) and maximum firepower (24+1).

Key Features

• Factory-installed Viper red dot sight with co-witness iron sights
• 4.32-inch cold hammer-forged threaded barrel (1/2x28 TPI)

• Optic-cut stainless steel slide in matching FDE finish
• Ambidextrous controls including slide stop and magazine release

The 509 Compact Tactical maintains consistent accuracy across various ammunition weights, with the longer sight radius and factory optic providing enhanced precision at extended ranges. The threaded barrel accepts standard 1/2x28 suppressors and muzzle devices without modification. Weather-resistant construction and proven FN reliability make this suitable for duty carry, competition shooting, and home defense applications.
