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, Oracle Arms 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.
