“Sawed-off firearm” means a shotgun with a barrel less than eighteen inches long, or a rifle with a barrel less than sixteen inches long, or a shotgun or rifle less than twenty-six inches long overall.
Yep. Illegal in Ohio. I'll stick to my $200 stamps thankyouverymuch.
You are assuming that it's still considered a "shotgun" with no stock. Are AR pistols illegal in OH? Nope, they are not, and they can have a barrel lengths less than 16".
