Class A is a High capacity permit. BUT, that gun would be illegal in Mass. unless is was manufactured prior to 1998. All high caps are banned unless they were manufactured prior to the high cap ban. I'm pretty sure G.O.A.L. has a link on their website for the state website of "approved" weapons. Before any gun manufacturer can sell a new model gun in MA they have to submit a certain number of them to the state, who will perform certain tests on them to determine their safety, etc. Also they can't be capable of accepting a high cap mag, so this means that when S&W wants to sell the sd40ve here, it has to have mods made to it so that it can't accept the mags that you have for YOUR sd40ve......... Also has to have a heavy trigger pull, I forget the exact pound of pull, but it's ridiculous. This state SUCKS. Many manufacturers refuse to submit their guns for testing, or to make a special model to be MA compliant. Many fine weapons that are out there for sale, are unavailable here.....
