I have been trying to find out on the web. Maybe I am not doing it right, but I am more confused now, that when I started my research. Was there ever a .25 ACP Thompson SMG???. I am sure I saw a picture of a full size thompson, with a .25 ACP version side by side. I have been researching, found nothing conclusive. Please help, and a picture would be really nice! thanks my fellow highroad men!:banghead:
