The cases that changed everything:

DC v Heller: https://www.oyez.org/cases/2007/07-290 (Listen to the oral argument.) District of Columbia v. Heller, 554 U.S. 570 (2008), was a landmark case in which the Supreme Court of the United States held that the Second Amendment protects an individual’s right to possess a firearm for traditionally lawful purposes, such as self-defense within the home. This case involved ordinances (the law) in the District of Columbia only. Thus, the Court’s opinion only applied to federal jurisdictions. Successfully argued by Alan Gura.
McDonald v. Chicago: https://www.oyez.org/cases/2009/08-1521 (Listen to the oral argument.)
McDonald v. Chicago, 561 U.S. 742 (2010), is a landmark decision of the U.S. Supreme Court that determined the Second Amendment also applies to the individual states. The Court held that the right of an individual to “keep and bear arms” is incorporated by the Due Process Clause of the Fourteenth Amendment and applies to the states. The decision cleared up the uncertainty left in the wake of Heller as to the scope of gun rights in regard to the states. Again, won by Alan Gura.

New York State Rifle & Pistol Association Inc. v. Bruen, https://www.oyez.org/cases/2021/20-843

The state of New York required a person to show a ‘special need’ for self-protection to receive an unrestricted license to carry a concealed firearm outside the home. Robert Nash and Brandon Koch challenged the law after New York rejected their concealed-carry applications based on failure to show “proper cause.”

Justice Thomas delivered the opinion of the Court. The right to carry a firearm in public for self-defense is deeply rooted in history, and no other constitutional right requires a showing of “special need” to exercise it. While some “sensitive places” restrictions might be appropriate, Manhattan is not a “sensitive place.” Gun restrictions are constitutional only if there is a tradition of such regulation in U.S. history. New York’s proper-cause requirement violates the Fourteenth Amendment by preventing law-abiding citizens with ordinary self-defense needs from exercising their Second Amendment right to keep and bear arms in public for self-defense.

Justice Samuel Alito authored a concurring opinion arguing that the effect of guns on American society is irrelevant to the issue.
