The law merely says that others are now firearms.If you want to believe a court will find that a pistol grip only shotgun is "intended to be fired from the shoulder" then there's no arguing with you. And if you want to register a clearly banned firearm with the state of New York of all places on your pistol permit so that NYSP knows exactly where to go to seize it if you're lucky and make a felony arrest if you're not then don't let me stop you.
Firearms are illegal in NY unless you have them registered on your pistol permit.
Where does it say you can't put one of these on your pistol permit ?
