OA Defense 2311 Pro Full-Size 9mm Pistol, Ported, 17/21-Round

The OA Defense 2311 Pro is a full-size 9mm pistol (brand part no. 2311FULLSIZEPROBLK) built around a DLC-coated, ported 5-inch stainless steel barrel. OA Defense combines the extended frame of the 2311 system with duty-driven enhancements engineered for hard use and high round counts, including a longer sight radius and increased grip surface for controlled, repeatable shooting. The ported barrel and tuned internals promote recoil management and consistent cycling, while a cut-and-contoured slide, enhanced trigger, and extended magazine release paddle reinforce a mission-ready setup. This kit ships complete with a polymer grip module, a 7075 aluminum magwell, three magazines, a Dawson Precision optics-ready RMR slide cut, factory sights, a range bag, and a cable safety lock.
