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 included three-magazine configuration reinforce its mission-ready setup. Fully ambidextrous controls, an optics-ready slide, lightning-fast cycle time, and a modular grip with 7035 aluminum magwell provide adaptable control and accuracy, ensuring the OA Defense 2311™ Pro remains prepared for duty, training, and adverse environments alike.

Each assembled pistol then goes through a multi-point inspection and test firing process prior to being released for cleaning and shipping. DELIVERY TIMES OA Defense strives to deliver pistol orders within ninety (90) days of ordering. The OA production team goes to great lengths to ensure that lead times do not exceed this timeframe, but variables do exist that are outside of our control. If the production team feels that additional time is needed to ensure that your pistol is leaving our facility in perfect condition, then we will contact you with an updated delivery estimate. For questions regarding lead times and delivery estimates beyond the standard 90-day window, please contact us.
