Gun laws in the United States by state

State level laws vary significantly in their form, content, and level of restriction. Forty-four states have a provision in their state constitutions similar to the Second Amendment to the U.S. Constitution, which protects the right to keep and bear arms. The exceptions are California, Iowa, Maryland, Minnesota, New Jersey, and New York. In New York, however, the statutory civil rights laws contain a provision virtually identical to the Second Amendment. Additionally, the U.S. Supreme Court held in McDonald v. Chicago that the protections of the Second Amendment to keep and bear arms for self-defense in one's home apply against state governments and their political subdivisions.
