Oa Defense 2311 Full Size Pro 9mm Blk/Gry Ported 17/21

The OA Defense 2311 Full Size Pro is a 9mm duty pistol built for shooters who demand reliable performance through high-volume range sessions and serious carry use. This full-size striker-fired platform combines practical features—integral V-porting on the barrel and slide, a contoured slide profile, and an enhanced trigger—to deliver faster follow-ups and smoother shooting without the bulk or complexity of a competition gun. The 2311 Pro ships as a complete kit with everything needed to get running: the pistol, five magazines (three 21-round and two 17-round), four interchangeable slide plates for optic mounting or iron sights, Night Fision tritium night sights, a Springer Precision extended mag release paddle, and a Savior Equipment range bag.

The ported barrel and slide work together to reduce muzzle rise, keeping your sight picture steady even when running +P self-defense loads. The Pro-grade trigger breaks between 3.5 and 4.0 pounds—lighter and smoother than OA's standard duty trigger—giving you the control needed for accurate, rapid fire. The lightened slide cycles faster, cutting your split times between shots. The progressive-texture polymer grip is comfortable for all-day shooting, and the 7075 aluminum frame keeps overall weight reasonable at 28 ounces unloaded.

Whether you're training for carry, running steel or paper competitions, or simply putting in volume at the range, the 2311 Pro arrives ready to perform. The included optic-mounting plates support RMR, DPP, and Holosun K/RMSc footprints, so you can add a reflex sight if your mission calls for it. The Night Fision sights come in standard height (for iron-only setups), intermediate height (for RMR-compatible plates), and suppressor-height front sight (for DPP). It's a no-compromise kit for serious shooters.
