So if the gun shop/mfr is unsure, who do they contact?Almost totally fruitless.
Also everyone needs to remember that in response to letters from Nate at Engage Armament (who is an attorney) the MSP has stated, in writing, that the list of firearms as banned or not banned on their site is NOT binding, and is merely "guidance" from the MSP. Anyone buying a firearm that may or may not be banned should consult the gun shop and or the manufacturer on that, according to the MSP.
I know there is no right answer to any of these questions. That was the point of the law....
