This HAVOC is built on Cosaint’s COS21 double-stack 1911-pattern frame and marked accordingly on the dustcover. The full-size grip module is textured polymer, paired with a large flared magazine well finished in blue for fast, confident reloads. Capacity is 15+1 with the included magazine.
The 5-inch Kart 9mm NM barrel is ported and match-marked on the hood, and works with a tri-top slide that includes lightening cuts and slide windows. Sighting is straightforward and adjustable: a fiber-optic front and an adjustable rear sight.
Controls are set up for precision single-action use, including an ambidextrous thumb safety and a beavertail grip safety. A flat-faced, lightened trigger and a skeletonized commander-style hammer round out the fire-control setup.
The dustcover integrates an accessory/light rail, and the slide is fitted with a C&H Precision optic-mounting plate. This two-tone pistol is a recent release from Cosaint Arms and notes an early, low serial within the HAVOC sequence.
