The FN 509 Tactical Threaded is a 9mm Luger semi-automatic pistol in the FN 509 family, built on a design that began as FN's submission for the U.S. Army Modular Handgun Trials. It is intended for duty, tactical and recreational shooting and features a polymer frame in a matte black finish.

The pistol has a 4.5-inch cold hammer-forged stainless-steel barrel with a target crown and 1/2x28 threads. It uses a DA/SA action, holds 10 rounds, weighs 1.74 pounds and has 3-dot night sights set at suppressor height. Its low-profile optics mounting system accepts more than ten miniature red dot optics that co-witness with the iron sights.
