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 OA 2311 Pro is the full-size ported powerhouse of the OA Defense line-up. Designed and optimized for duty use and high round count range days, the OA 2311 Pro delivers maximum performance, accuracy, and reliability even under the harshest conditions. Integral V-porting in the 5″ barrel and slide reduce muzzle rise with minimal sight picture obstruction, even with +P self-defense ammunition. The Pro cut lightened slide profile increases cycle speed for faster follow-up shots and decrease split times. 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. With five magazines and four slide plates included in the kit, the OA 2311 Pro 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.

OA Defense strives to deliver pistol orders within ninety (90) days of ordering. The OA production team goes to great lengths to ensure that lead times do not exceed this timeframe, but variables do exist that are outside of our control. If the production team feels that additional time is needed to ensure that your pistol is leaving our facility in perfect condition, then we will contact you with an updated delivery estimate.
