The Auto-Ordnance Thompson 1927A1 is most famously referred to as the Tommy Gun. It comes chambered in the hard hitting American classic caliber of .45ACP. The Thompson was built for World War I, but finished too late. It was marketed to law enforcement and the military without much interest. The Tommy Gun ended up being widely accepted by people in organized crime and received most of it's nicknames from that world. The Tommy Gun has made appearances throughout history on both sides of the law. The blued metal finish and walnut furniture take you back to a forgotten age, and you can almost smell the gunpowder and bootleg liquor. This one has both a stick mag and a drum, but the drum is pretty finicky getting in and out.
