The FN 509 Midsize Tactical is a red dot-ready and suppressor-ready 9mm semi-automatic pistol built for practical use and higher-round-count training. It combines a compact midsize frame with a cold hammer-forged stainless steel threaded barrel, recessed target crown, and FN Low-Profile Optics-Mounting System. Suppressor-height 3-dot night sights provide a clear aiming reference, including when a compatible suppressor is installed. Fully ambidextrous controls, improved front and rear cocking serrations, an external extractor, loaded chamber indicator, flat-faced trigger, and MIL-STD-1913 accessory rail support confident handling. This configuration includes a Holosun 407C Red Dot, two magazines, a case, locking device, and owner's manual.
