OA Defense OA 2311 Full Size

The OA 2311 is OA Defense's full-size 9mm, built for duty use and serious defensive shooters. OA Defense aims it at law enforcement and anyone who wants a full-length pistol that shoots fast and stays accurate. This is the standard model, the starting point for the full-size 2311 line.

It uses a 5-inch stainless steel barrel, and the full-length frame gives it good balance and a long sight radius for steady shot placement. The frame is 7075 aluminum. The grip module is polymer, and a 7075 aluminum magwell comes on the full-size model. OA Defense also includes a Handle-it Edge grip kit, so you can add texture where you want it.

The trigger breaks at 3.5 to 4 pounds, helped by OA Defense's upgraded G2 hammer and sear kit. For sighting, you get Dawson Precision parts across the board: a fiber optic front, a fixed rear, and an optics kit for RMR-footprint red dots.

The numbers are friendly for a full-size gun. It's 8.5 inches long, 5.25 inches tall and 1.78 inches wide, and it weighs 29 ounces unloaded. Two 17-round magazines come in the box.

OA Defense makes the 2311 in America, with gunsmiths hand-fitting the critical parts before every pistol is inspected and test fired. It all comes in a custom OA Defense range bag. If you want a modern full-size double stack for duty or home defense that doesn't cost what a custom 2011 does, the OA 2311 deserves a look.
