The Hi-Point Firearms model C9 is chambered for 9 mm Luger ammunition. The frame of the single-action, semi-automatic handgun is lightweight polymer and its slide is constructed of aluminum alloy. A detachable magazine holds eight rounds. Standard factory sights are three-dot design with full windage and elevation adjustment at the rear sight. Hi-Point's recommended schedule calls for disassembling and reassembling the C9 to perform regular preventative maintenance at approximately 1,500-round intervals.
