There is absolutey no doubt about what the Founding Fathers intent was with the 2nd Amendment. it is evidenced over and over in their writings:
"Firearms stand next in importance to the Constitution itself. They are the American people's liberty teeth and keystone under independence." --George Washington
"[T]he people are not to be disarmed of their weapons. They are left in full possession of them."
--Zacharia Johnson, speech in the Virginia Ratifying Convention, 1788
"We established however some, although not all its [self-government] important principles. The constitutions of most of our States assert, that all power is inherent in the people; that they may exercise it by themselves, in all cases to which they think themselves competent, (as in electing their functionaries executive and legislative, and deciding by a jury of themselves, in all judiciary cases in which any fact is involved,) or they may act by representatives, freely and equally chosen; that it is their right and duty to be at all times armed."
--Thomas Jefferson, letter to John Cartwright, 1824
