The other side counters: what if the weapons in question had been bazookas instead of sawed-off shotguns?

I believe that this is a straw man argument. A bazooka is a crew served weapon. So are belt fed machineguns, F-16s and atomic bombs. The 2nd Amendment was meant to protect and defend the rights and duties of individuals. If it takes more than one person to carry or operate a weapon it is a crew served weapon and not an individual rifleman's weapon. If the 2nd amendment protects individual rights, then the logic is pretty clear.
I have also read that there were discussions when the Articles of Confederation were adopted over whether an individual could own a cannon as a personal firearm. Nope, crew served. I wish I had a dollar for every time I've heard libs and anti-gun bugs play this as what they think is a trump card.

Back then, individuals owned crew served ships loaded down with cannons. Your argument doesn't quite work.

How I love the smell of crew served weapons in the morning. ;o)
Good to see you posting Brucifer. By the way, the move is on for Saturday!
