The Firearms Control Regulations Act of 1975 was passed by the District of Columbia city council on June 29, 1976,[1][2] and went into effect September 24, 1976.[3] The law banned residents from owning handguns, automatic firearms, or high-capacity semi-automatic firearms, as well as prohibited possession of unregistered firearms. Exceptions to the ban were allowed for police officers and guns registered before 1976. The law also required firearms kept in the home to be "unloaded, disassembled, or bound by a trigger lock or similar device";[4] this was deemed to be a prohibition on the use of firearms for self-defense in the home.[5] On June 26, 2008, in the historic case of District of Columbia v. Heller, the Supreme Court of the United States determined that the ban and trigger lock provisions violate the Second Amendment.
Section 7-2507.02, like the bar on carrying a pistol within the home, amounts to a complete prohibition on the lawful use of handguns for self-defense.
