OA Defense 2311 Compact 9mm Pistol, Black/Stainless 15+1

The OA Defense 2311 Compact (brand part no. 2311COMPACTSTBLK) blends 2311 platform engineering with a controlled, concealable frame built for everyday carry and personal defense in 9mm. A stainless steel barrel and precision-tuned internals keep the pistol cycling consistently under stress, while a modular polymer grip with a 7075 aluminum magwell gives shooters a fast, confident reload. Fully ambidextrous controls and an optics-ready, serrated slide make this compact 2311 as much at home on the range as it is on the belt. Backed by the upgraded OA Defense G2 hammer and sear system, it delivers a clean, predictable trigger break shot after shot.
