First Look: FN 503 Slim-Profile 9mm Pistol

Ideal for concealed carry, the FN 503 weighs just 21 ounces, is 1.1 inches wide, and utilizes a striker-fired design. Inspired by the features present in FN 509 series pistols, the 503 delivers impressive accuracy, dependable performance, and easy concealment. A 3.1-inch barrel with recessed crown aids in the accuracy department, while enlarged controls and soft recoil make the FN 503 comfortable and controllable to shoot. 

The FN 503 comes with 509-style low-profile iron sights and ships with a six-round mag with pinky extension, as well as an eight-round mag with grip sleeve. Likewise, the handgun comes with skateboard tape grip and an all-metal trigger that breaks between 5-7 pounds.
