    This ideal combination of a four-inch slide and barrel with a midsize frame retains full-sized pistol performance in an easily-concealed package. The 9mm pistol ships standard with 15-round capacity and is compatible with all FN 509 magazines with use of a sleeve. The improved controls aid in manipulation, the new improved texturing on the two included backstraps provides better recoil management and a new, flatter faced trigger allows for more controllable trigger press and cleaner break.
