The OA 2311 Pro stands as the full-size, ported powerhouse of the OA Defense lineup, meticulously designed for duty use and high-round count training days. Engineered to deliver unmatched performance, exceptional accuracy and unwavering reliability, it thrives under even the most demanding conditions. The integrated V-porting in the 5 inches barrel and slide effectively reduces muzzle rise, ensuring minimal sight picture disruption, even when firing +P self-defense ammunition. The Pro-cut, lightened slide profile increases cycle speed, enhancing follow-up shot speed and reducing split times for a more efficient shooting experience. With an enhanced trigger treatment, the OA 2311 Pro features a slightly lighter pull than the standard duty model triggers, providing a smoother trigger break that improves both accuracy and overall feel. Equipped with five magazines and four slide plates, the OA 2311 Pro comes complete with everything you need to optimize your performance and take your shooting to the next level.
