509 Midsize 9mm 4in 15 + 1 Black Semi Auto Pistol

The FN 509 Midsize is a 9mm semi-automatic pistol designed to provide full-size performance in a more easily concealed package. Its four-inch cold hammer-forged stainless steel barrel uses a recessed target crown, while the polymer frame includes a MIL-STD-1913 accessory rail and interchangeable backstraps for a more secure, comfortable grip. A flatter-faced trigger, improved cocking serrations, and easily manipulated controls support confident handling. The standard configuration has no manual safety and uses 3-dot luminescent sights for quick target acquisition. Two 15-round magazines are included.
