Tommy gun

The Tommy gun is a nickname for the Thompson submachine gun that appear in Fallout 2, the Fallout: New Vegas add-on Honest Hearts, Fallout 4 and Fallout Tactics: Brotherhood of Steel,.

Background
The Thompson submachine gun has been around since the 1920s and has been used for law and crime alike. Though high prices stifled civilian purchases of the firearm, the United States military deployed the Thompson throughout World War II and the Korean Wars. Mobsters with enough disposable income were also able to purchase this beauty. This tradition weathered the Great War, as evident by the many mobsters strolling through New Reno with a Tommy gun in their hands.
