Yes, large-capacity gun magazines are legal in the United States. There is no federal law that prohibits the manufacture, sale, or possession of high-capacity magazines. However, certain states and localities have enacted laws limiting the size of magazines that can be possessed or sold within their jurisdictions. For example, California generally prohibits the sale of gun magazines capable of holding more than 10 rounds of ammunition.
So if you’re looking to purchase a high-capacity magazine, it’s important to first check the laws in your state or locality to make sure you’re not breaking any rules. But in general, there’s no federal law prohibiting large-capacity gun magazines.
