The FN America compensated barrel kit (brand part no. 20100807) upgrades the FN 509 Compact with a factory-matched 9mm barrel and compensator finished in flat dark earth. It pairs a black barrel with an FDE compensator, giving Compact-frame 509 owners the same muzzle-taming hardware first introduced on the FN 509 CC Edge. Because the compensator measures roughly 4.34 inches, it adds only a modest amount of length while helping tame muzzle rise on a defensive or range pistol. This kit is a straightforward way to add compensated performance to an FN 509 Compact without a full pistol swap.
