This submachine gun was designed by William Daniel-Douglas Hammond of Los Angeles, California. His patent for the weapon was originally assigned to the Machinery Sales Company of Los Angeles and was later picked up by the Auto-Ordnance Company of Thompson fame. Made up primarily of steel stampings with a tubing receiver, the Thompson T2 was considerably easier to make than any of the original Thompson submachineguns. For additional ease of manufacture, the design also used the already standard Thompson box magazines. Instead of a selector switch, the weapon had a pivoting trigger that could be used to fire either full or semi automatically.
Several components of the T2 broke during testing. Compared to the M2 submachine gun, the T2 has 60 stoppages and the M2 only 2. The accuracy of the T2 was also considered inferior to the designs already in use. Only about 6 prototypes of the T2 were produced, reportedly half of those being chambered for the 9mm Parabellum round.
