The FN 509 Midsize Tactical is a multi-role 9mm suited for concealed carry, home defense, and duty use. Its full-hand 15-round grip frame and included 24-round magazine give you capacity for carry and high round-count training, while the 4.5" cold hammer-forged stainless steel barrel is threaded 1/2"-28 for suppressors. The FN Low-Profile Optics Mounting System accepts most red dots in minutes, and suppressor-height 3-dot night sights co-witness with most optics.
