FN America 509 MRD
About the FN America 509 MRD
The FN America 509 MRD is FN America’s optics-ready 9mm pistol, available in Compact and Fullsize frames with a direct-mount cut for red dots and barrel lengths from 3.7" to 4.5". Capacity runs 10, 15, or 17 rounds depending on configuration, with both black and flat dark earth in stock, including a version that ships with a Holosun 407C red dot pre-mounted. If you’re building a carry or duty pistol around a red dot from day one, this is FN America’s most direct answer — ask Miami Guns about the pre-mounted-optic option.
