Fn 509 Midsize Tactical, 9mm Luger, 4.50" Barrel, 10+1 Capacity, Matte Finish

The FN 509 Midsize Tactical builds on FN's Tactical pistol family, offering a mid-size 9mm Luger striker-fire platform with a 10+1 capacity and a 4.50" black target crown, threaded steel barrel that is suppressor-ready for shooters who plan to add a can, and an optic-ready serrated steel slide for red-dot systems; its matte black polymer frame with Picatinny rail, ambidextrous controls, and interchangeable backstraps deliver a balance of concealability and duty-ready capability for concealed carry, home defense, and duty use. The ergonomics and weight distribution provide a “just-right” recoil impulse and fast sight acquisition compared with smaller pistols, while the smooth trigger breaks around 5 pounds for controllable follow-up shots. Sight configuration includes 3-dot night sights with suppressor-height rear for co-witnessing optics, and the threaded barrel features a target crown for accuracy. This FN model is aimed at shooters who want a versatile, durable handgun from the FN 509 series that's optics- and suppressor-ready; firearm transfers require processing through a Federal Firearms License (FFL) holder.
