Built to deliver uncompromising performance in a full-size fighting platform, the OA Defense 2311 Pro combines the extended frame of the 2311 system with duty-driven enhancements engineered for hard use and high round counts. The longer sight radius and increased grip surface support controlled, repeatable shooting, while the DLC-treated, ported barrel and tuned internals promote durability, recoil management and consistent cycling under demanding conditions. Featuring an enhanced trigger; extended magazine release paddle; ambidextrous controls; an optics-ready slide, and a modular grip with 7035 aluminum magwell provide adaptable control and accuracy. Includes one 21rd and two 17rd magazines.
