FN 509C Threaded Barrel with Compensator 9mm Luger 4.35" Black

Overview

The FN 509 Compensator Accessory Kit for the 9 Compact pistol includes a 4.34-inch cold hammer-forged barrel and a proprietary, quick-detach compensator. The barrel utilizes non-threaded mounting lugs, allowing the compensator to be attached and removed without the use of tools. The compensator is machined from stainless steel with a PVD finish and features V-style ports that redirect gases and flash away from the shooter’s field of view. This system is designed to reduce muzzle rise by up to 25 percent and decrease felt recoil, resulting in flatter shooting and improved control during follow-up shots. The barrel features a 1:10-inch twist rate with a polished chamber and feed ramp for reliability. It utilizes the pistol's original factory recoil spring and retains a consistent sight picture through the use of the compensating ports.
