FN America unveiled their new FN 509 variant, the Midsize Tactical during last weekend’s NRA Annual Meeting in Houston.
It combines their full size tactical slide cut with the Low-Profile Optics-Mounting System and midsize grip frame. The 4.5″ barrel is cold hammer forged and threaded.
Offered in Flat Black and FDE, it comes with a 15-round magazine but FN also offers a 24-round magazine.
