Here is the deal. Nobody that I now of has ever been prosecuted SOLELY on the VG issue (just like the hi cap thing during the ban). However, it does get tacked on from time to time and is used as a bargaining chip, to be thrown out for co-operation. The ATFE has "ruled" that the VG makes it an AOW even though by virtue of their own definition of AOW the rifled barrel excludes any rifled barrel pistol from being an AOW unless the weapon does not look like a firearm (pager and pen guns). The ATFE's reasoning is since the addition of the second grip, in their mind, makes the gun no longer designed to be shot one handed and therefore it is no longer a pistol (like my 4 pound Encore .50 AK is really designed to be shot one-handed?), even though it CAN still be shot one handed. It makes no since at all and their reasoning so far as I know has not been tested. While a judge might preliminarily rule that they do not consider the second grip an AOW that ruling has not to my knowledge been handed down in case law. The AOW part is always dropped before a final ruling is handed out which IMO would likely establish precedence that the second grip does NOT make it an AOW. Thing is, do you want to be the test case? And, can you afford to fight the ATFE? And what if you lose? Is it really worth it to YOU?
