Microstamping is a proprietary ballistics identification technology. Microscopic markings are engraved onto the tip of the firing pin and onto the breech face of a firearm with a laser. When the gun is fired, these etchings are transferred to the primer by the firing pin and to the cartridge case head by the breech face, using the pressure created when a round is fired. After being fired, if the cases are recovered by police, the microscopic markings imprinted on the cartridges can then be examined by forensic ballistics experts to help trace the firearm to the last registered owner. A California law requiring the use of microstamping technology in all new semiautomatic firearms sold in the state has attracted controversy.
District of Columbia v. Heller, 554 U.S. 570 (2008), is a landmark decision of the Supreme Court of the United States. It ruled that the Second Amendment to the U.S. Constitution protects an individual's right to keep and bear arms—unconnected with service in a militia—for traditionally lawful purposes such as self-defense within the home, and that the District of Columbia's handgun ban and requirement that lawfully owned rifles and shotguns be kept "unloaded and disassembled or bound by a trigger lock" violated this guarantee. It also stated that the right to bear arms is not unlimited and that certain restrictions on guns and gun ownership were permissible. It was the first Supreme Court case to decide whether the Second Amendment protects an individual right to keep and bear arms for self-defense or whether the right was only intended for state militias.

McDonald v. City of Chicago, 561 U.S. 742 (2010), was a landmark decision of the Supreme Court of the United States that found that the right of an individual to "keep and bear arms", as protected under the Second Amendment, is incorporated by the Fourteenth Amendment and is thereby enforceable against the states. The decision cleared up the uncertainty left in the wake of District of Columbia v. Heller (2008) as to the scope of gun rights in regard to the states.

Assault weapons legislation in the United States refers to bills and laws that define and restrict or make illegal the manufacture, transfer, and possession of assault weapons. How these firearms are defined and regulated varies from jurisdiction to jurisdiction; generally, this constitutes a list of specific firearms and combinations of features on semiautomatic firearms.
A high-capacity magazine ban is a law which bans or otherwise restricts detachable firearm magazines that can hold more than a certain number of rounds of ammunition. For example, in the United States, the now-expired Federal Assault Weapons Ban of 1994 included limits regarding magazines that could hold more than ten rounds. As of 2022, twelve U.S. states, and a number of local governments, ban or regulate magazines that they have legally defined as high-capacity. The majority of states do not ban or regulate any magazines on the basis of capacity. States that do have large capacity magazine bans or restrictions typically do not apply to firearms with fixed magazines whose capacity would otherwise exceed the large capacity threshold.
A high-capacity magazine is a magazine capable of holding a higher than normal number of ammunition rounds for a particular firearm.

Miller v. Bonta is a pending court case before Judge Roger Benitez of the U.S. District Court for the Southern District of California concerning California's assault weapon ban, the Roberti–Roos Assault Weapons Control Act of 1989 (AWCA).

A three-judge panel of the Ninth Circuit issued a stay of the ruling on June 21, 2021, which left the ban in place as appeals were litigated. The panel then vacated Judge Benitez’s ruling and remanded it back down after NYSRPA v. Bruen was decided. The case was known as Miller v. Becerra before Rob Bonta succeeded Xavier Becerra as Attorney General of California in April 2021.
