OA Defense 2311 9mm 5" Black 17+1 OA-2311-FLSZ-KIT-BLK-STD-17

OA Defense 2311

The OA Defense 2311 is a semi-automatic 9mm pistol built to combine race gun speed with duty grade durability. This black full size configuration uses a 5 inch barrel, a 7075 aluminum frame, a polymer grip, and 17+1 capacity. The kit includes the pistol, three 17-round OA magazines, four slide plates, Night Fision tritium night sights, a cable safety lock, and a custom OA Defense range bag.

Each 2311 is hand fit at critical engagement points and test fired before shipping. The trigger is specified at 4.0 to 4.5 pounds, and the slide plate set covers iron sights plus RMR, DPP, and Holosun K/RMSc optic footprints. Standard height Night Fision tritium sights are installed, and a suppressor height front sight is included for use with the DPP plate. At 8.50 inches long and 29 ounces unloaded, the pistol stays full size without excess bulk.

This 2311 kit is suited to law enforcement, duty, competition, and defensive use where a 9mm with multiple optic options is required. The extra magazines and range bag make it ready for training out of the box. Combined with interchangeable plates and night sights, it is built for fast, accurate shooting that can hold up to regular hard use.
