While the Jackhammer does more damage than the H&K CAWS and has both greater range and damage than the NeoStead Combat SG, it lacks the ability to make targeted shots which both of those shotguns have. However, it does have a lower strength requirement, making it easier to wield without the use of drugs.
- Kansas City, in a chest.
- In the Merchant special encounter, it can be stolen from some of the raider guards.
- Sometimes it can be pickpocketed from Andrew "No-one" Smith, at Bunker Delta.
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 three) were ever made. The game stays true to the weapon's reputation of controllability, even with automatic fire.
