Description
FN’s 509 Midsize MRD delivers serious capability in a gun that won’t wear you out all day. The stainless steel slide is machined for direct optic mounting and features aggressive serrations for positive handling, while the polymer frame with integrated Picatinny rail lets you add a light or laser. At 26.5 ounces with a 4-inch barrel and 7.4-inch overall length, it balances shootability with carryability. The DAO trigger is smooth and consistent, co-witness iron sights keep you zeroed if your optic goes down, and the included pair of magazines plus interchangeable backstraps mean you can tailor the gun to your hand. This is purpose-built for defensive carry, sport shooting, or duty use.
