Beretta M9A4 G 9mm 5.1″ FDE | 18rd | JS92M9A4GM

The Beretta M9A4 G is a full-size 9mm semi-automatic service pistol that brings modern features to the long-standing M9 platform. It has a 5.1-inch threaded barrel, a flat dark earth Cerakote aluminum frame with aggressively textured Vertec-style thin grips, an optic-ready serrated slide, and dovetailed tritium night sights. The pistol uses a single/double action mechanism with a de-cocker and a 18-round magazine capacity. For a compatible optic under $1,000, a compact micro red-dot such as the Holosun 507C is a practical match; confirm the correct mounting plate for the pistol’s proprietary slide cut before purchase.
