FN America LLC has announced the release of the smallest addition to the FN 509 family of pistols , the FN 509 Compact MRD , an optics-ready compact pistol featuring the company's patented FN Low-Profile Optics-Mounting System, further expanding the optics-ready FN 509 models to four.
The FN 509 Compact MRD is chambered in 9mm and is striker-fired. It features a 3.7-inch barrel and compact slide, and is available in both black and flat dark earth (FDE) finishes. FN says the patented optics mounting system allows for a low-profile, direct mount through a carefully developed plate system that perfectly positions the optic so that the focal point allows for a low-profile mount and co-witness with the all-black iron sights that minimize interference with the optic.
