The Military Armament Corporation MAC RA9 is a full-size, striker-fired 9mm pistol built around the RA9 Monoblock System, a serialized fire-control chassis designed to support interchangeable grips and slides. The modular chassis provides the foundation for the RA9 family while allowing the pistol to evolve as additional configurations and accessories. The standard RA9 combines the Monoblock chassis with a textured polymer grip module; optics-ready slide and ambidextrous controls to create a versatile base configuration for range, defensive, and general-purpose use. Includes pistol case, two 17rd magazines with metal base plates, mag loading tool, RMR optic adapter plate; cleaning kit and firearm lock.
