Which auto ordnance Thompson model is the authentic to ones in WW2?

The Auto Ordnance Thompson Model 1928A1 is the most authentic replica of the original Thompson submachine gun used in World War II. It is a semi-automatic firearm that closely resembles the military-issued version in terms of appearance, weight, and handling characteristics. This model features a select-fire switch that allows users to change between safe, semi-automatic, and full-automatic modes of fire (depending on local laws and regulations). However, it is important to note that the availability of fully automatic versions may vary among countries due to legal restrictions on civilian firearms.
