The FN 509 Midsize blends a full-size 4" barrel and slide with a shorter, easier-to-conceal midsize grip frame, giving you full-caliber 9mm performance in a package that carries comfortably all day. It's an ideal choice for everyday carry, duty use, or range training where control and concealability both matter.
Fully ambidextrous slide stops and magazine release make the 509 Midsize equally at home for right- or left-handed shooters. The flat-faced trigger delivers a consistent, clean break, while improved slide serrations and aggressive frame texturing help you run the gun confidently under recoil. Two interchangeable backstraps let you tune the grip to your hand.
The Flat Dark Earth finish covers both the stainless steel serrated slide and the polymer frame, and an integrated Picatinny accessory rail accepts lights and lasers. This configuration ships with two 15-round magazines and is compatible with all FN 509 magazines using a sleeve.
