Contra Costa County, California prohibits the use of firearms equipped with red dot sights and/or weapon mounted lights for permitted concealed carry. It likewise prohibits all single action only firearms, including the venerable 1911 (and subsequently the 2011) platform. Both firearms equiped with electronic sights like red dots, as well as those equipped with flashlights, are in common use for self-defense all over the country. So too, are single action only platform firearms like 1911’s, which have been amongst the most popular firearms in the country for lawful uses, including self-defense for over a century. Contra Costa County simply does not have the authority to prohibit its residents from using these arms for lawful – and constiutionally protected – self-defense.
On June, 17, 2026, Second Amendment Foundation, joined by two Contra Costa residents, filed suit, alleging Contra Costa’s policies violated the Second and Fourteenth Amendment to the United States Constitution.
