The Pancor Jackhammer is a fully automatic, rotary magazine, 12 gauge shotgun. Designed in 1984 by John Anderson, who continued to develop the weapon through the 90's. The concept of a fully automatic shotgun has not taken hold with the military, or with law enforcement, due to the difficulty of controlling such a weapon.
Magazine function as an Anti-Personnel MineEdit
As an interesting additional feature, it is possible to take the drum magazine off the firearm, attach a detonator, and use it as an anti-personnel mine that fires all of the cartridges at once when tripped. The manufacturer advertised this as the "Beartrap."
