The OA Defense 2311 is a duty-ready 9x19mm pistol built for shooters who demand speed, accuracy, and adaptability. This full-size striker-fired platform combines a 17-4 stainless steel slide with a durable 7075 aluminum frame, chambered in 9x19mm with a 5-inch barrel and 17+1 round capacity. It's optic-ready from the factory, ships with multiple mounting plate options, and comes configured with Night Fision tritium night sights—making it equally at home on the range, in competition, or as a duty carry piece.

What sets the 2311 apart is its completeness out of the box. This kit includes three 17-round magazines, a suite of night sight configurations (standard, intermediate, and suppressor height), and mounting plates for RMR, DPP, and Holosun K/RMSc footprint optics. That means you're not hunting for accessories or compatibility specs—you can mount your preferred red dot and go. The ambidextrous controls make it equally accessible whether you're right- or left-handed, and the 4.0–4.5 lb trigger breaks clean and predictably.

At 29 ounces unloaded with compact 1.78-inch width, the 2311 balances shootability with manageable recoil and reliable 9mm performance. Whether you're training hard, running duty, or stacking rounds downrange, the black DLC finish on the slide resists corrosion and pairs cleanly with the black polymer grip. The kit includes a cable safety lock, owners manual, and a custom OA Defense range bag—everything new owners need to get started responsibly.
