Guide to Laws About Weapons in California

Gun
You have a right to own a firearm for lawful purposes (like self defense), and the government may not unnecessarily restrict this right. However, like most rights, the right to own a firearm is NOT absolute, and the government may place SOME restrictions on it.1U.S. Constitution, 2nd amendmentDISTRICT OF COLUMBIA v. HELLER (2008)
478 F. 3d 370

California and Los Angeles have some of the strongest gun control laws in the country, which we list here. And because of the unfortunate frequent mass shootings, particularly school shootings, gun laws in California are getting stricter.
