The OA Defense 2311 Pro S 9mm 5" 21rd Black is a full-size, single-action pistol built around the extended 2311 frame for demanding shooters who expect consistent performance. Its DLC-coated, ported 5" stainless steel barrel works with a cut-and-contoured slide to manage recoil and maintain smooth cycling, while the polymer grip module and 7035 aluminum magwell provide secure, repeatable control during long training sessions or high round counts.

This model’s optics-ready, serrated slide with Dawson Precision fiber optic front sight and fixed rear sight supports fast sight acquisition on the range or in competition. Fully ambidextrous controls, an upgraded OA Defense G2 hammer and sear kit, enhanced trigger, and extended magazine release paddle make the pistol adaptable for a wide variety of shooters and applications, from structured practice to everyday training. Thoughtful engineering and attention to detail reflect OA Defense’s focus on modern craftsmanship and innovation in duty-ready sidearms.
