Owners of the OA 2311 Pro in Desert Sage point to the package contents as the primary draw. Getting 5 magazines, a case, 4 optic plates, and tritium sights in a single purchase is the argument most buyers make when comparing it against alternatives that charge separately for each accessory.

The Sage grip paired with the Desert Tan frame gives the pistol a distinctive two-tone appearance. Opinions on the color combination split between those who specifically sought it out for the look and those who focused entirely on the functional package. The 5-inch ported barrel draws the same split as across the OA Defense 2311 line: competitive shooters appreciate the gas ports, while some owners prefer an unported muzzle for carry use.

The 21-round magazines are consistently praised as a practical capacity advantage. Build quality discussion mirrors the broader OA Defense 2311 product family, with most owners reporting positive results and a smaller number noting that a few external surfaces benefit from break-in use.
