OA 2311 specific holsters are available from Dara Holsters, and are in development by U.S. Duty Gear. Compatibility with existing holsters may vary, but many holsters designed for light-bearing Sig P320 models are also compatible with the OA 2311 provided that the appropriate weapon light is installed.

Most P320 magazine basepads are compatible with the OA 2311. At this time, the only known non-compatible products are extensions from Killer Innovations.

Technical

Historically, the Achilles heel of a finely-tuned 1911 platform was the tendency to jam or malfunction if dirt or debris got trapped between the moving components of the action. In order to combat this vulnerability, OA Defense has engineered patent-pending grooves into key areas of the action and the frame. The location and orientation of these grooves allows the OA 2311 to self-evacuate dirt and debris, reducing the chance of it getting lodged in the action and causing a malfunction.

Select parts and components will be available for sale through our custom shop beginning some time in 2024. Repairs and service work will need to be performed by a certified OA 2311 gunsmith in order to maintain coverage under the Limited Lifetime Warranty.
