FN 509 MRD w/ Optic Features
The heart of this model lies in its black PVD-coated optic-cut slide, ready to accept a wide array of red dot optics. The included Holosun HS 407C offers crisp, reliable sighting with long battery life and shake-awake technology. Suppressor-height co-witness iron sights ensure backup targeting capability and align perfectly with the optic for enhanced aiming speed and confidence.
The black polymer frame features interchangeable backstraps and a built-in Picatinny accessory rail, offering ergonomic comfort and tactical customization. The hammer-forged stainless steel barrel with a recessed target crown enhances accuracy and durability. Weighing just 27 oz, the FN 509 MRD delivers a balanced feel in the hand, and the consistent double-action-only trigger pull (4.5–6 lbs) ensures precision under pressure. Designed with no manual safety, this model is streamlined for fast, intuitive deployment.
