I agree, how about this description of a pistol grip?
"A pistol grip, forward grip, or any other grip or stock, the use of which would allow an individual to grip the weapon in such a way that any finger on the trigger hand, in addition to the trigger finger, would be directly below any portion of the action of the weapon when firing"
The definition of a barrel shroud would include all free float tubes.
I am not sure what firearms would not need to have a certificate similar to the pistol purchase permit under this bill.
