This variant ships with a \u003cstrong\u003eFlat Dark Earth\u003c\/strong\u003e PVD-coated optic-ready steel slide featuring front and rear serrations, paired with a matching FDE polymer frame machined with an integrated \u003cstrong\u003ePicatinny accessory rail\u003c\/strong\u003e. The \u003cstrong\u003e15+1\u003c\/strong\u003e capacity lands this midsize offering between the compact FN 509 and the full-size FN 509 Tactical, giving shooters a balance of concealability and shootability comparable to a Glock 19 in overall footprint.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe MRD (Miniature Red Dot) configuration adds the FN Low Profile Optics Mounting System, allowing direct mounting of more than ten popular micro red dots without the need for adapter plates. Black co-witness iron sights come installed from the factory so the pistol is range-ready even before an optic is added. The slide is cut with a precision optic pocket, and the slide plate is easily swapped to match the footprint of the chosen dot.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003e\u003cstrong\u003eFully ambidextrous\u003c\/strong\u003e controls include a reversible magazine release and ambidextrous slide stop levers, making the 509 Midsize MRD equally intuitive for left- and right-handed shooters. There is \u003cstrong\u003eno manual external safety\u003c\/strong\u003e; instead the pistol relies on its DAO trigger system with a built-in trigger safety for carry. The grip features \u003cstrong\u003eFDE interchangeable backstraps\u003c\/strong\u003e so the hand fit can be tuned without tools.
