For what it's worth....among the discussion, is this little nugget of the "intelligence" used to determine what is banned (but read the whole article for some specifics):
Edited to add:At first, he thought the M1-Carbine would be safe, but then he googled a picture of it. Basically, if he saw a magazine sticking below the body of the gun, and if it is a semi-auto, it's banned.
He specifically brought up the Kel-Tec KSG as an example of something that they wanted to ban even though it's not semi-auto, so even though the bullet points on Diane's website don't mention extended tubes on pump guns or any other features like pistol grips on them, that doesn't mean they're going to be safe if she gets her way.
