Iotian submachine gun

The Iotian submachine gun was the primary hand-held submachine gun projectile weapon in use on the planet Iotia in the later 2260s decade. Because of a Prime Directive violation where a piece of literature, Chicago Mobs of the Twenties, was left behind on the world, the design of the Thompson submachine gun from Earth was used as the planform for these weapons.

The Iotianss, highly imitative, had sufficient technology to produce numerous examples of this weapon based on the design information in the carelessly shared book. 


 * Unless the book gave the Iotians a broad range of information about actual firearms and industrial materials processes of Earth's 20th century, these guns were probably made in a different manner than the ancient weapons they were based on.
