FN 509 Review: Better Than A M&P Or Glock?
The FN 509, originating from the Army's MHS program, offers a 9mm package with a 17-round capacity and a 4-inch barrel. It features a crisp 7lb trigger with a distinct wall and reset, ambidextrous controls, and aggressive texturing. While generally reliable, it experienced issues with specific polymer-cased ammunition. The design is noted as a 'mullet gun' with a compact slide on a full-size grip.
