The OA Defense 2311 Pro is a full-size, duty-grade semi-automatic pistol built for shooters who demand uncompromising performance under the most demanding conditions. Chambered in 9mm and featuring a DLC-treated, ported 5″ barrel, this full-size fighting pistol delivers exceptional recoil management, consistent cycling, and an extended sight radius that supports accurate, repeatable shot placement round after round.

Engineered on the proven 2311 platform, the 2311 Pro features a cut-and-contoured slide, enhanced trigger, extended magazine release paddle, and fully ambidextrous controls — making it an ideal choice for both right- and left-handed operators. The optics-ready slide ensures seamless compatibility with a wide range of modern red dot sights, while the modular grip and 7075 aluminum magwell provide a secure, customizable interface for high-round-count training and duty use. Each pistol ships with three 21-round magazines, reinforcing its mission-ready configuration from the moment it leaves the box.

Whether you’re a law enforcement professional, a serious competitor, or a dedicated defensive shooter seeking a full-size pistol with refined ergonomics and proven durability, the OA Defense 2311 Pro is purpose-built to perform when it matters most.
