Designed by Pancor, the Jackhammer combat shotgun is one of the most powerful pre-War close range weapons. It is essentially a gas-operated revolver, using a bullpup configuration. Placing the magazine behind the trigger group allowed the designers to make it more compact and better balanced without compromising accuracy or ability to control it in automatic mode.[1]
Characteristics
Jackhammer is a peculiar weapon. It ranks above the Neostead Combat SG and the H&K CAWS in terms of damage and range, however, it cannot make targeted shots. However, it has a lower Strength requirement to boot, making it good for close quarters combat.
Locations
Kansas City: Inside a chest in the mutant compound.
Merchant special encounter: Carried by raider guards, can be stolen.
Behind the scenes
The Pancor Jackhammer was a prototypical automatic shotgun that was designed in 1984 and patented in 1987, though it never entered production as its target audience (military and police forces worldwide) never placed an order for these weapons and Pancor went bankrupt.
