ATTENTION: As of 10/2/2024 with the passing of the H.4885 gun law, requirements in Massachusetts have been drastically re-written. Check out our article here on how that impacts Semi-Auto Shotgun ownership.
Additionally, since all firearms sold in MA must now be on approved rosters, and there are none available for long guns, The Commonwealth of Massachusetts Executive Office of Public Safety and Security has stated that under the Act and 501 CMR 7.00, dealers may continue to sell shotguns and rifles so long as they are not otherwise prohibited in Massachusetts, pending further guidance from the Firearms Control Advisory Board.
A semi-automatic shotgun is a repeating shotgun with a semi-automatic action, i.e. capable of automatically chambering a new shell after each firing, but requires individual trigger-pull to manually actuate each shot. Semi-automatic shotguns use gas operation, blowback, or recoil operation to cycle the action, eject the empty shell, and load another round.
