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

The OA Defense 2311 Full Size Pro is a 9mm duty pistol built for shooters who demand flat shooting and fast follow-ups. This ported full-size 9mm is purpose-built for high-round-count range sessions and professional use, combining a finely tuned trigger with aggressive recoil management to help you shoot tighter groups and recover between shots faster than a standard duty weapon.

What sets the 2311 Pro apart is its integral V-porting in both the 5-inch barrel and slide—a setup that genuinely reduces muzzle rise without cluttering your sight picture, even when running hot self-defense loads. The lightweight Pro-cut slide cycles faster, feeding follow-up shots quicker and cutting split times. If trigger feel matters to you, the enhanced Pro trigger breaks at 3.5–4.0 pounds, delivering a smoother, more predictable break than standard mil-spec units and helping you shoot more accurately under pressure.

The grip module wears progressive texturing across a black polymer frame built on a 7075 aluminum slide—tough enough for duty work, refined enough for competition. This kit arrives with everything most shooters need: five magazines (three 21-round, two 17-round), four swappable slide plates for different optic footprints (RMR, DPP, Holosun K/RMSc), Night Fision tritium night sights in three heights, a Springer Precision extended mag release paddle, cable lock, and a Savior Equipment range bag. Whether you're building your first full-size duty pistol or upgrading from a 9mm that doesn't quite keep up, the 2311 Pro delivers raw capability without the corporate polish—just a gun that works.
