Whether used by hero or villain, this is one iconic, badass firearm, even the fictional Captain America partner Bucky Barnes used with great effect on the silver screen. It doesn't matter who is firing it or if it's just on display, the Thompson submachine gun is one wicked cool piece of firearms history. From prohibition era gangsters and outlaws to cops and WWII heroes, the Thompson has become a legitimate icon of American firearms lore and even mythology. I recently held a Thompson (but didn't get to fire it) and I have to say, yes, I did feel pretty badass...
