Design and Key Features
The FN 509 MIDSIZE MRD [BLK] uses a polymer frame to reduce weight and improve corrosion resistance, making it practical for daily carry. The midsize configuration gives you a 4-inch barrel and a shortened grip that eases concealment without severely compromising sight radius or controllability. The pistol ships with two 15-round magazines and is offered at a street price of $660.99.
Controls and Fit
Ambidextrous controls and interchangeable backstraps let shooters tailor the grip profile to hand size and shooting style. The shortened grip balances concealability with magazine capacity — a strong compromise for those who want higher-capacity carry without a full-size frame.
Optic-Ready Slide and Sights
The MRD series features an optic cut on the slide designed to be used with FN’s adapter plates and is paired with suppressor-height iron sights for proper sight co-witness. That optic-ready platform simplifies mounting a red dot while retaining usable iron sights for fast transitions and redundancy. Note: this model has no manual safety, so training and proper holstering practices are essential.
Performance Considerations
Expect duty-level durability from the FN 509 MIDSIZE MRD [BLK] thanks to its modern striker-fired internals and FN’s pedigree. The combination of a 4-inch barrel, compact grip, and 15-round magazines makes it a versatile option for defensive carry, range work, and professional use.
For shooters prioritizing an optic-ready, high-capacity midsize pistol with adaptable ergonomics, the FN 509 MIDSIZE MRD [BLK] is a strong candidate. Check current availability and view product details and pricing on the shop page to complete your evaluation.
