Choosing a service-grade defensive pistol means balancing reliability, ergonomics, and sighting systems that work under stress. For duty and personal defense, the right striker-fired midsize option can deliver controllable recoil, durable construction, and sights you can trust in low light.
FN 509 MIDSIZE (DEMO) [BLK] follows FN’s evolution from the FNS line into a modern striker-fired platform optimized for duty and defensive roles. Built with a polymer frame for reduced weight and improved corrosion resistance, this Midsize variant pairs a 4-inch barrel with a shortened grip for easier concealment while retaining a 15-round magazine capacity.

Design and Controls
From a tactical perspective, the FN 509 MIDSIZE (DEMO) [BLK] emphasizes ambidextrous controls and modular ergonomics. Interchangeable backstraps allow shooters to tune grip circumference and hand fit, improving natural point of aim and trigger reach for a wide variety of users. The all-black finish reduces glare and aids concealment in operational settings.
Sights and Sight Picture
One standout detail is the 3-dot style luminescent sights. These provide a consistent sight picture in low-light scenarios without relying on batteries, making them a dependable backup when rapid target acquisition matters. The 4-inch barrel maintains a balance of sight radius for accuracy while still being friendly to concealed carry rigs.
Capacity, Carry, and Condition
Included is one 15-round magazine, giving a solid capacity without pushing to full-size grips. Because these are manufacturer demonstration models, expect possible signs of handling and light use—an acceptable trade for shooters seeking value at a price of $469.99.
