This AXG Combat configuration features the metal AXG grip module with an integral beavertail and a detachable flared magwell. The grip panels are textured brown with SIG SAUER logos, and the frame wears an FDE hard-coat anodized finish. Ambidextrous slide catch levers and a MIL-STD-1913 accessory rail on the dust cover round out the handling and mounting options.
The 4.75 inch carbon-steel barrel is extended and threaded 1/2x28, capped by a knurled thread protector. Barrel hood markings confirm 9mm x 19 and the thread pitch. The stainless-steel slide has a black Nitron finish, front and rear serrations, and an optics cut with a cover plate installed; the rear sight is mounted to the plate.
Factory suppressor-height tritium night sights include an XRAY3 front with a green ring and a two-dot tritium rear for clear day/night aiming. The fire control setup uses a flat, skeletonized trigger within a striker-fired, locked-breech, short-recoil action, and there is no manual safety.
Capacity is noted at 21+1. Three 21-round steel magazines are included, each with extended base pads and a Made in Italy marking. Country of origin is USA.
