California’s newly proposed gun laws would:

1. 
   
2. Ban the possession of ammunition magazines that hold more than 10 rounds
   
3. Prevent the future sale, purchase, manufacture, importation, or transfer of any firearms that can accept detachable magazines
   
4. Close the "bullet button" loophole by banning tools that allow the quick changing of gun magazines
   
5. Regulate ammunition sales like the state regulates gun sales. Ammunition dealers would need to be licensed and anyone buying from them would need to obtain a permit and complete a background check.
   
6. Create a 5-cent tax on each bullet purchased, for the purpose of funding crime prevention
   
7. Prevent felons and other adults barred from gun ownership from living in a house that contains any guns
   
8. Prohibit the loaning or sale of a firearm between people who know each other personally
   
9. Take steps to phase out legal possession of assault weapons that were purchased before California outlawed their sale
   
10. Require all firearms owners to take an hours-long gun safety course every year, similar to what the state now requires for obtaining a concealed weapon permit
    
11. Require gun owners to purchase insurance to cover damage they may inflict
    
12. Require CalPERS and CalSTRS, two of the nation's largest pension funds, to divest from companies that make, sell, or market firearms or ammunition
    

California has already enacted some of the nation’s strictest gun control laws, partly due to its experience with a Sandy-Hook-style massacre: In 1989, a mentally unstable ex-con opened fire with an AK-47-style assault rifle on an elementary school playground in Stockton, killing five schoolchildren and wounding 28 others. The shooting contributed to the passage that year of California’s assault weapons ban.
