FN 66100463 509 Midsize 9mm Luger 4" Barrel 15+1, Matte Black Polymer Frame With Mounting Rail, Matte Black Steel Slide, No Manual Safety
Upgrade your EDC with the FN 509 Midsize. 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 improved controls aid in manipulation, while the improved texturing on the two included backstraps provides better recoil management and a, flatter faced trigger allows for more controllable trigger press and cleaner break.
Its polymer constructed frame features fully ambidextrous controls, MIL-STD-1913 accessory mounting rail and cold hammer-forged stainless steel barrel with a recessed target crown. The slide is easily racked, and features combat-style sights and improved front and rear cocking serrations.
The 509 Mid-Size ships with two interchangeable backstraps and FN logo soft pistol case. This model has a black finish, 3-dot luminescent sights, and comes with two 15-round magazines.
