I'm thinking of getting a gun in 40 cal and after doing much research I like what I've heard of the Springfield XD. Now I know it's not on the Mass approved list, but I occasionally see them for sale on the classifieds section. I understand that you can purchase a gun not on the list if it was made before 1994, but can someone explain how it's legal to purchase one that was made later than that. Just trying to follow the laws as absurd as they are.
