OA Defense 2311 Pro Elite 9mm – Full-Size, Ported 5-Inch Barrel, Optics-Ready, 21+1 Capacity
The OA Defense 2311 Pro Elite is a modern, competition-tuned take on the classic 1911, built around a hybrid 2311 frame that accepts SIG P320 double-stack magazines for 21-round capacity. A ported 416R stainless steel barrel, DLC-coated and paired with a lightened slide, keeps recoil flat and cycle times quick. Fully ambidextrous controls, co-witness tritium night sights, and a multi-footprint optics interface make this full-size pistol ready for duty, range, or match use right out of the case.

Details
The 2311 Pro Elite blends 1911 single-action fire control with a modular, double-stack grip module machined from 7075-T6 aluminum. This architecture delivers familiar 1911 trigger feel while boosting capacity to 21+1 rounds.
Its 5-inch ported 416R stainless barrel and lightened, optics-cut slide are both finished in black DLC for durability and corrosion resistance. The porting and top-side slide window work together to vent gas upward, reducing muzzle rise and improving split times.
Controls are fully ambidextrous, including the thumb safety and slide stop. An extended paddle-style magazine release speeds reloads, while the integral flared mag-well guides fresh magazines home.
A flat-faced, skeletonized trigger breaks clean in single-action. Sighting duties are handled by co-witness-height Night Fision tritium front and a serrated, drift-adjustable rear, both cut to clear most popular red-dot footprints.
The dust-cover carries a 7-slot MIL-STD-1913 rail for weapon lights or lasers, rounding out a feature set aimed at shooters who demand modern capacity and modularity without sacrificing classic 1911 ergonomics.
