FN 509 Midsize
The FN 509 Midsize will enhance your EDC. With a four-inch slide and barrel and a midsize frame, this perfect setup maintains full-sized pistol performance in a discrete package. The standard magazine capacity for the 9mm pistol is 15, and it can be used with any FN 509 magazine by using a sleeve. The new, improved texturing on the two included backstraps provides better recoil management, and the new, flatter-faced trigger allows for a more manageable trigger push and cleaner break. The updated controls help with manipulation.
