Maybe if you are arguing on the merits of actual technical specs, but in terms of cinematic icon appeal the only other sub machine gun that comes close to the Thompson would be the Uzi. Honestly how many people can identify an MP40 or Sturmgewehr on sight, but I guarantee almost anyone will recognize a Thompson and can at least identify the connection to Mafia and organized crime.xmetatr0nx said:the better guns are the MP40 and the sturmgewehr 44, sadly they arent ever put on film because of their unpleasant backgrounds.
Of coarse now this has me thinking about all the most cinematic firearms. Pistols is a toss up between the Colt 45 Single Action Army Revolver and the Colt 1911. While the Western has lost some of it's appeal over the years, I think the "Peacemaker" is on most people's minds when it comes to revolvers. The Colt 1911 has been used almost as frequently in movies as it has been in service. Although I think the Berrata might be moving to replace it in the semi-automatic pistol category.
For rifles I think I am going to hearken back to the Western again, while it's rarely seen today the Winchester is till probably the most recognized rifle that your average person could identify and place. Assault Rifle is easy. It has to be the AK-47, no contest really. No assault rifle is more widely known or can be instantly equated to certain groups and feelings about such.
