The RA9 features a striker-fired action and is built around the Monoblock chassis system designed to support interchangeable grips and slides to give users a fully modular pistol. Each pistol has fully ambidextrous controls and comes optic-ready out of the box with an mounting cut on the slide and an included RMR adapter plate. This model comes in a full-size configuration and features a 4.25" barrel. Two 17-round magazines are included along with a cleaning kit.
