Pancor Jackhammer (Fallout 2)

The Pancor Jackhammer combat shotgun is a small gun in Fallout 2.

Locations

 * Very rarely, it is possible to find these shotguns on the mainland, wielded by Enclave soldiers. It can also be found on several characters in NCR that can be killed for missions, making at least two easily attainable before level five.
 * Roger Westin has one

Behind the scenes
In real life, the Jackhammer was a prototype design that failed to reach full-fledged production due to its manufacturer's bankruptcy. Very few functional prototypes (according to some reports, as few as two) were ever made. The game stays true to the weapon's reputation of controllability, even with automatic fire.
