The OA Defense 2311 Pro 9MM 5" Ported Barrel delivers a modern take on the double-stack 1911-style pistol, blending a full-size aluminum frame with a modular polymer grip and extended magwell for confident control. Its DLC-coated, V-ported 5" stainless steel barrel and cut slide work together to manage recoil and keep the sights flat for fast, repeatable shots, while Dawson Precision fiber optic front and fixed rear sights provide a crisp sight picture right out of the box. Designed as a versatile full-size sidearm, the 2311 Pro is well suited for range work, training, and competition-focused shooters who want a refined single-action trigger and high-capacity magazines. The optics-ready slide with Dawson Precision RMR cut makes it easy to add a red dot, and fully ambidextrous controls support a wide range of shooters. OA Defense’s attention to detail, tuned internals, and duty-focused enhancements showcase the brand’s commitment to precision and reliability. Key Features:
