LEGACY MODEL NOTICE
This pistol is a legacy OA Defense model and is no longer available for purchase directly through our website.
This page remains available as a reference for previous purchasers and those looking for product specifications, features, and details.
For current models available directly through OA Defense, please explore our latest lineup.
The Legacy OA 2311 Compact Pro is the ultimate EDC and personal defense platform; optimized to provide maximum speed, accuracy, and control in all conditions. The contoured lightening-cut slide and barrel porting reduce felt recoil and minimize muzzle rise, even with +P self-defense ammunition. The progressive texture on the polymer grip provides traction where you need it most while minimizing discomfort for AIWB carry applications. The enhanced Pro trigger treatment yields a slightly lighter trigger pull than the standard duty model triggers, facilitating an even smoother trigger break for increased accuracy and feel. The Legacy OA 2311 arrives with everything you need to maximize your performance
HIGH DESERT FINISH
Bred in the mountains of the “Battle Born” state, our new High Desert Finish for the OA 2311 pays homage to our Nevada heritage and our function-first design ethos. This treatment pulls its color palette from the arid deserts and sage-covered mountains that surround our headquarters here in Dayton. Finished in Cerakote Elite E-190, the High Desert Finish can be ordered with either a black grip or a sage green grip to complete the pistol.

PRECISION BRED THROUGH PROCESS
Proudly Made in America | OA Defense’s production and assembly process relies on precision engineering and machining, multiple rounds of stringent quality control, and a team of skilled techs and gunsmiths who work together to hand-fit and hand-finish the critical engagement points. Each assembled pistol then goes through a multi-point inspection and test firing process prior to being released for cleaning and shipping.
