FN 509 MIDSIZE (DEMO) [BLK]

Design and sighting system

The Midsize variant is built on the proven FN foundation, carrying a 4-inch barrel and a shortened grip to aid concealment without sacrificing sight radius or control. The pistol features 3-dot style luminescent sights that provide fast target acquisition in low light—an essential defensive advantage. The polymer frame reduces weight and improves corrosion resistance for daily carry or duty use.

FN designed ambidextrous controls and interchangeable backstraps into the 509 to accommodate a wide range of hand sizes and shooting grips. The shortened grip profile of this Midsize model maintains concealability while accepting a 15-round magazine—striking a practical middle ground between capacity and size.

Durability and handling

The polymer frame resists corrosion and keeps overall weight down for all-day carry. Note that these particular units are manufacturer demonstration models and may show signs of handling or light use; they still represent a cost-effective way to acquire a duty-style platform.
