You would have to buy it from an individual who owned the gun IN MA. Given it's not on the AG's list that would mean they moved into the state with one and were willing to sell it.
Good luck and sadly welcome to MA's 'approved list' BS.
You mean the one with the funny looking rail on the barrel i dont think you can get it in ma unless your a dealer, so dealers can have "unsafe" handguns but we cant, i dont get it
