Welp, here we go again. http://thomas.loc.gov/cgi-bin/query/z?c109:H.R.1312: notice these sections when reading. This was the big stink back when Kerry tried to pass this the last time. Their definition of pistol grip is so vague that it literally covers anything used as a grip by the user. That includes standard riflestock grips as well. Also this part leaves it open to the government as to what is a sporting firearm and what's not.
