Gun laws in Connecticut regulate the sale, possession, and use of firearms and ammunition in the U.S. state of Connecticut. Gun laws in Connecticut are amongst the most restrictive in the country. Connecticut requires training, background check and permitting requirements for the purchase of firearms and ammunition; and a ban (with exceptions) on certain semi-automatic firearms defined as "assault weapons" and magazines that can hold more than 10 rounds. Connecticut's licensing system for concealed carry is relatively permissive.
