Hi, pro gun leftist here: -all pretty equal in terms of lethality, they all fire the same ammunition. They may have slightly different bullet velocities based on barrel length but that doesn’t matter in the context of your question -the clearly NFA-illegal one just has a short barrel, which means you could hide it under a trench coat. A lot of these rules are from the old mafia days and were written to prevent mobsters running around with tommy guns etc. Rules against briefcase guns and stuff
