Originally, the Bill of Rights only applied to the federal government, not the states. It wasn't until the Fourteenth Amendment was passed that certain amendments started getting "incorporated against the states," meaning that they applied to the states as well as the federal government. For instance, it wasn't until Near v. Minnesota in the 1930s that the Supreme Court held that states were limited by the Fourteenth Amendment in their ability to institute prior restraints on the press.
That didn't happen to the Second Amendment until McDonald v. City of Chicago (or arguably DC v. Heller, but McDonald made sure everyone knew it) in 2010.
Constitutionally speaking, the Second Amendment has never been stronger.
