Design and Handling
Built as a successor to FN’s FNS series, the FN 509 MIDSIZE MRD [FDE] *10-ROUND* is FN’s modern striker-fired duty and defensive pistol. Its polymer frame reduces weight and improves corrosion resistance for consistent carry. The midsize configuration pairs a 4-inch barrel with a shortened grip for easier concealment without sacrificing sight radius or control. At a street price of $699.99, it targets users who want duty-grade features in a carry-friendly package.
Sights, Optics, and Accessory Readiness
This MRD variant includes an optic-cut slide compatible with FN adapter plates and comes fitted with suppressor-height 3-dot luminescent sights to allow proper co-witness when an optic is mounted (optic not included). The MRD cut simplifies installing micro red dots while preserving iron-sight usability for fast transitions and adverse-condition shooting. If you prefer a dot, plan for FN-compatible adapter plates and verify footprint before purchase. View product details and pricing
Ergonomics and Controls
Ambidextrous controls and interchangeable backstraps make the pistol adaptable across hand sizes and shooting styles. The lack of a manual safety streamlines the manual of arms for defensive use, while the two included 10-round magazines support common magazine capacities for restricted jurisdictions or compact carry setups. The FDE finish offers low-visibility advantages in natural environments and a distinct tactical appearance.
For shooters seeking a capable, optic-ready midsize pistol from a trusted manufacturer, the FN 509 MIDSIZE MRD [FDE] *10-ROUND* delivers a practical blend of concealment and precision at $699.99.
