OA Defense 2311 Pro 9mm | 5″ Ported | Optic Ready

The OA Defense 2311 Pro is a full-size, optics-ready 9mm pistol built around a 2311 platform frame with duty-oriented features intended for high-round-count use. It pairs a ported, DLC-coated 5″ barrel with tuned internals, an extended sight radius and a modular grip for repeatable control. For an optic that pairs well without exceeding $1,000, use a red-dot in the RMR footprint such as the Trijicon RMR series.

Common applications: duty or training and precision-focused range work where a longer sight radius and magazine capacity options are desirable.
