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 5″ barrel and tuned internals promote durability, recoil management, and consistent cycling under demanding conditions. A cut-and-contoured slide, enhanced trigger, extended magazine release paddle, and a three-magazine configuration reinforce its mission-ready setup. Fully ambidextrous controls, an optics-ready slide, lightning-fast cycle time, and a modular grip with a 7035 aluminum magwell provide adaptable control and accuracy, ensuring the OA Defense 2311 Pro remains prepared for duty, training, and adverse environments alike.<\/p>\n","protected":false},"excerpt":{"rendered":"
