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.
This Thompson M1928 submachine gun is a sinister looking weapon; every time you hold it, you have an urge to put on a fedora hat and crack your knuckles. The Thompson is well-fed by a large 50 round drum magazine. Like the "Grease gun", the Thompson is pretty powerful, but fires nondescript .45 caliber rounds.
A venerable relic, the .45 Auto submachine gun is a classic design that rivals the .45 Auto pistol in age. Originally designed for trench warfare of World War I, this weapon's craftsmanship and firepower made it a popular choice for Prohibition-era gangsters, policemen, and U.S. military units. It is a conventional open bolt, magazine fed design. While heavy for its size, the metal and wood used in its manufacture make it extremely durable. Many units were kept in storage by the United States Army and National Guard, eventually finding their way into the hands of various groups across the wasteland after these armories and ammo dumps were looted. The most notable groups include the White Legs, who adopted them as Storm Drums and use them extensively in their raids, and the Triggermen of the Commonwealth.
