The FN 509 Compact Tactical delivers suppressor-ready capability in a concealable package, combining FN's military-proven design with tactical enhancements for civilian use. This compact pistol features a factory-threaded barrel and optics-ready slide configuration that eliminates the need for aftermarket modifications.

What Makes This Different

Unlike standard compact pistols, the 509CT comes factory-equipped with a threaded barrel and optics cut, saving hundreds in gunsmith fees. The Flat Dark Earth PVD coating provides superior corrosion resistance compared to standard finishes, while the ambidextrous controls accommodate both right and left-handed shooters without modification. FN's cold hammer-forged barrel delivers match-grade accuracy in a duty-sized package.
