Patience is a Virtue: Thompson Submachine Gun was Worth the Wait

Appearing in American cinema films from The Devil’s Brigade to Bonnie & Clyde, a Thompson submachine gun with a drum magazine has joined the mythos of America. Sold primarily to the military and law enforcement, “Tommy guns” were also purchased by private citizens. With the fictionalized and serialized tales of the “mob vs. G-men,” it became part of our collective conscience.

Tommy gun

In the first part of March 1990, I joined the staff of the Museum Division of the State Historical Society of North Dakota. Within days, our senior curator, Norman C. Paulson, told me of a Thompson submachine gun at the North Dakota State Penitentiary that had been "promised" to the State Historical Society by the former and current warden when they decided to surplus or transfer the gun.

Paulson and James E. Sperry, State Historical Society superintendent, had been informed about the Thompson as early as 1968. Former prison guards had sporadically kept Paulson informed about the gun from 1973 into the 1980s. Since Norman was on the verge of retiring, it now fell to me to “keep my ears open” about that gun. The torch had been passed, and I continued to “keep my ears open” and wait. After 50 years, on Sept. 11, 2018, the submachine gun was transferred to the State Historical Society by the Penitentiary. Truly, good things had come to those who wait.

  • Length: 33.7 (860 mm)

It has three magazines:

Stick magazine

Two XX-Type 20-shot stick magazines. These were preferred by law enforcement because they do not jam.

Drum Magazine

One L-Type 50-round Thompson drum magazine. Popular in American fiction, this magazine can jam the action, rendering the gun useless.
