OA Defense 2311 Pro Full Size 9mm 5" 21rd Ported Pistol

The 2311 Pro is OA Defense's full size duty gun, built on a 2011 pattern double stack frame rather than a polymer chassis. The frame is aluminum with a Picatinny rail under the dust cover, the slide is steel and cut for an optic, and the 5 inch barrel is DLC treated and ported. Porting bleeds gas upward at the muzzle, which flattens the pistol in recoil and helps keep a red dot inside the window between shots.

Controls are ambidextrous and the magazine release paddle is extended, which counts on a gun running 21 round magazines. OA fits an enhanced trigger and a modular grip over an aluminum magwell that funnels a reload in. Against the shorter guns on the same platform, the full size frame gives a longer sight picture and more grip surface to hold onto, and both make the pistol easier to shoot quickly under time. The slide carries serrations for a positive hold when press checking. Three magazines come in the box, one 21 round and two 17 round, so there is enough on hand to run a class or a match without buying more.
