Ban possession of large-capacity ammunition magazines

Minnesota's SF 3714 bans possession of large-capacity ammunition magazines (defined as devices holding more than 10 rounds, excluding permanently altered devices, .22 caliber tubes, or lever-action tubular magazines). The law prohibits most people from owning, manufacturing, transferring, or possessing these magazines, with exceptions for law enforcement, military personnel, and licensed dealers selling to those entities. Current owners must surrender, permanently alter, or remove their magazines by July 1, 2027, and violations carry felony penalties of up to 5 years in prison or $25,000 fines. The bill takes effect July 1, 2026, applying to offenses committed on or after that date.
