FN 509 Tactical 9mm 4.5" Threaded Barrel Matte Black

Introducing the FN 509 Tactical, a firearm that stands as a testament to precision engineering and tactical versatility. This pistol is an extension of the renowned FN 509 family, rooted in innovation from FN's submission for the U.S. Army’s Modular Handgun Trials. It carries forward enhancements that elevate its performance and adaptability.

The hallmark of this model is FN’s patented Low-Profile Optics Mounting System. With it, you can seamlessly integrate over ten different commercially available miniature red dot optics onto your handgun without needing to mill the slide directly—a feature that ensures co-witness with suppressor-height night sights and readiness for future upgrades.

Even when shooting without an optic, functionality remains uncompromised thanks to a robust slide cap equipped with raised sight wings. These protect your iron sight alignment during inadvertent drops or impacts while providing a textured surface ideal for racking against various surfaces like belt loops or boot heels.

At its core lies an FN-signature 4.5-inch cold hammer-forged stainless-steel barrel designed for exceptional accuracy and durability. The target crown features ½” x 28 threads compatible with most 9mm suppressors on the market today, complemented by a thread cap integrated with an O-ring ensuring stability under rigorous use.

This pistol doesn’t just meet expectations—it sets new standards in reliability and adaptability for both seasoned shooters and newcomers alike who demand nothing less than excellence from their sidearm.
