Similar to a M3A1 "grease gun" SMG, the usage of this gun is limited by its rather heavy ammunition. Furthermore, the grease gun has better damage, longer range, and only needs 4 AP to fire. The Tommy gun compensates for the drawbacks with a larger magazine.
- Shark Club and Desperado bouncers carry them.
- Found in various random encounters in the area around New Reno.
- Eldridge stocks the gun.
The bouncers' "rifle" animation frames match this weapon, likely because they are not intended to carry anything that is not a Tommy gun.
