Gun laws in Massachusetts regulate the sale, possession, and use of firearms and ammunition in the Commonwealth of Massachusetts in the United States.[1][2] These laws are among the most restrictive in the entire country.
On July 25, 2024, Maura Healey, the Governor of Massachusetts, signed An Act Modernizing Firearms Laws (H.4885) described as "the state’s most significant gun safety legislation in a decade."[3][4] Changes per H.4885 are due to go into effect 90 days from the date of signing—October 23, 2024.[5]
