ARTV—Review: FN509
This review of the FN 509 highlights its features as a full-size, striker-fired, polymer-framed semi-automatic pistol chambered in 9mm. Key technical specifications include its dimensions, weight, and a double-action striker system with a trigger pull calibrated between 5.5 and 7.5 pounds. The review emphasizes FN's commitment to ambidexterity with controls on both sides and details the four passive safety systems. Ergonomic improvements over the FNS line are noted, along with the inclusion of a Picatinny rail and a replaceable backstrap system. The sights are described as 3-dot with photoluminescent elements, and a visual loaded chamber indicator is present.
