Updated the OP by listing all attorneys for each case.
2009_gunner, The various States Firearms Freedom Acts, are not really 2A cases. They are legislation challenging the current broad definition of the Commerce Clause. The Montana case is one such law that is being litigated in federal court.
The Wisconsin case, is a 2A case. When I have a few more details, I will add it to the list. Thank you for bringing this to my attention.
