Fn 509 Mrd 9mm Luger 4.5in 17+1 Capacity Matte Physical Vapor Deposition Finish

The FN 509 MRD is a full-featured, duty-grade 9mm Luger pistol from FN's renowned 509 series, and it blends a rugged 4.5" barrel and 27 oz. carry weight with a 17+1 capacity to deliver controllable recoil and extended shooting sessions for duty, home defense, or serious range work. The double-action striker-fired design provides a consistent 4.5—6.0 lb. trigger pull and a 1:10" RH twist for reliable bullet stabilization; the slide comes optic-cut and serrated for quick red-dot installation and positive manipulation, while the matte black PVD finish and black polymer grips stand up to hard use and the elements. At 7.9" overall length with a 6.3" sight radius and a slim 1.35" width the 509 MRD balances shootability and carryability for those who need a service-style platform that transitions well between competition drills and defensive encounters. There is no manual safety, favoring a streamlined draw and presentation, and this model requires an FFL transfer. If you're evaluating semi-auto pistols for law-enforcement duty, concealed carry with a larger-capacity option, or consistent range training, the FN 509 MRD's combination of capacity, optic-ready slide, and workmanlike ergonomics makes its role in a practical handgun lineup easy to understand.
