The OA 2311 Pro is the full-size, ported powerhouse in the OA Defense lineup, engineered for duty use and high round count training days. Built to excel under the toughest conditions, it offers exceptional performance, accuracy and reliability. Featuring integral V-porting in the 5 inches barrel and slide, the design effectively reduces muzzle rise with minimal disruption to the sight picture, even when firing +P self-defense ammunition.

An enhanced Pro trigger treatment delivers a slightly lighter pull compared to standard duty models, creating a smoother trigger break for improved accuracy and a more refined feel. The OA 2311 Pro comes equipped with five magazines and four slide plates, ensuring you have everything needed to maximize your shooting performance.
