Ok, just so I can wrap my head around this:
A shotgun that is Pistol-Grip only is considered a pistol, no matter what the barrel length is? And if so, does one have to be 21 to purchase said pistol-gripped shotgun?
I'll chalk this up to another law made by politicians who have no idea what in the **** they are talking about.
I guess it all comes down to what FEDERAL LAW defines as a "pistol". If a pistol-grip only SG is defined to be a pistol by FEDERAL LAW then yes they would have to be 21 to buy from a FFL. (NOTE: you can still buy one from a private party at 18 either way, since IN law allows an 18 YO to buy a handgun. It is only FEDERAL LAW that prevents you from buying a handgun from a FFL under 21).
This law was not made by said politicians. It was interpreted that way by the IN court of appeals:

I would have to look up the definitions to say one way or another.
EDIT:
Looking at the "definitions" section of Title 18 section 921, it would appear that a PG only SG is a "Handgun" by federal law:
(5) The term “shotgun” means a weapon designed or redesigned, made or remade, and intended to be fired from the shoulder...
(7) The term “rifle” means a weapon designed or redesigned, made or remade, and intended to be fired from the shoulder...
(29) The term “handgun” means—
(A) a firearm which has a short stock and is designed to be held and fired by the use of a single hand...
Unless it falls under some other obscure category.
Any FFL's that might want to weigh in.
