From page 15 of the decision:
“In sum, the Courts of Appeals’ second step is inconsistent with Heller’s historical approach and its rejection of means-end scrutiny. We reiterate that the standard for applying the Second Amendment is as follows: When the Second Amendment’s plain text covers an individual’s conduct, the Constitution presumptively protects that conduct. The government must then justify its regulation by demonstrating that it is consistent with the Nation’s historical tradition of firearm regulation. Only then may a court conclude that the individual’s conduct falls outside the Second Amendment’s “unqualified command.” Konigsberg, 366 U. S., at 50, n. 10.”
