Fabrique Nationale (FN) is inviting its customers to upgrade their everyday carry set with the new FN 509 Midsize 9 mm Luger semi-automatic pistol. Like the standard 509, the Midsize sports a 4" barrel. However, the polymer grip frame has been trimmed down by 0.36" to make the pistol easier to carry concealed. This pistol ships with 15-round magazines but will accept 17- and 24-round 509 magazines with the use of a sleeve. The slide is topped with fixed three-dot luminescent sights and features front and rear slide serrations. The cold-hammer-forged stainless steel barrel features a recessed target crown with a polished chamber and feed ramp. The polymer frame is outfitted with replaceable steel slide rails, an enhanced grip texture, interchangeable backstraps and an integral MIL-STD-1913 accessory rail. Other features include an improved, flatter trigger face and bilateral slide stops and magazine releases. fnamerica.com
