To protect residents from unsafe handguns that are more prone to accidental discharge, lack safety devices, and may be prone to firing when dropped, the Council of the District of Columbia identified the California Roster of Handguns Certified for Sale (also known as the California Roster of Handguns Determined Not to be Unsafe) as a source list for safer handguns. Handguns on the roster have passed firing, safety, and drop tests and are certified for sale in California by the California Department of Justice. The Chief of Police is authorized to periodically revise, by rule, the roster of handguns permissible for sale.
