To protect the lives and safety of law enforcement officers from the threat posed by ammunition capable of penetrating a protective vest when fired from a handgun, the Gun Control Act of 1968 (GCA), as amended, prohibits the import, manufacture, and distribution of "armor piercing ammunition" as defined by the statute. Interpreting the meaning of this statutory language, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has developed a framework that will apply to requests seeking a determination that certain projectiles qualify for this "sporting purpose" exemption.
