The FN 509M Tactical takes tactical performance to the next level in a compact and concealable form. Built for adaptability, this mid-size 9mm pistol features a 4.5-inch cold hammer-forged barrel with a 1/2x28 threaded muzzle and cap, making it suppressor-ready right out of the box. Its matte black finish is long-wearing and rugged, paired with suppressor-height tritium night sights and a factory-installed Holosun 407C red dot for precise aiming in any lighting condition. The polymer frame supports full ambidextrous controls and FNs advanced Low-Profile Optics-Mounting System for seamless optic integration.
