The 17-4 stainless steel construction is heat-treated to a Rockwell C hardness of 40-44, providing the ideal balance of toughness and machinability for a reliable slide. The Nitride finish penetrates the metal surface, creating a layer harder than chrome that reduces friction on the rails. This combination is proven in duty and competition use, engineered for the high-pressure 9mm Luger cartridge and sustained firing cycles.
