Abstract: A strengthened firearm includes at least one metal/composite material formed into at least one firearm component, and a polymer/composite material combined with the at least one firearm component. The metal/composite material replaces the polymer/composite material in a specific area or component of the firearm that may be weak or tend to fail earlier than other areas or components of a polymer/composite firearm. The method of combining the multiple materials allows for additional strength in the firearm.
