548 (CA4 1974); Cody v. United States, 460 F.2d 34 (CA8), cert. denied, 409 U.S. 1010 (1972) (the latter three cases holding, respectively, that 1202 (a) (1), 922 (g), and 922 (a) (6) do not violate the Second Amendment). Printz v. United States (1997) (concurring opinion of Thomas) Our most recent treatment of the Second Amendment occurred in United States v. Miller, 307 U.S. 174 (1939), in which we reversed the District Court's invalidation of the National Firearms Act, enacted in 1934. In Miller, we determined that the Second Amendment did not guarantee a citizen's right to possess a sawed off shotgun because that weapon had not been shown to be "ordinary military equipment" that could "contribute to the common defense". Id., at 178. The Court did not, however, attempt to define, or otherwise construe, the substantive right protected by the Second Amendment. District of Columbia v.
