Semi-automatic shotgun
Repeating shotgun with a semi-automatic action From Wikipedia, the free encyclopedia
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.[1] Semi-automatic shotguns use gas operation, blowback, or recoil operation to cycle the action, eject the empty shell, and load another round.[2] The first semi-automatic shotgun was the Automatic-5 by Browning.[3][1][4]

Many semi-automatic shotguns also provide an optional manual means of operation such as by pump action or a charging handle.
