What governs the regulation of high-capacity magazines?

The regulation of high-capacity magazines is primarily governed by state laws that limit magazine capacity. Each state has the authority to establish its own laws regarding firearms and their accessories, including magazines. Some states have put specific limitations on the number of rounds a magazine can hold in an effort to promote public safety and reduce gun violence. These laws can vary widely from state to state, with some imposing strict limits on capacity while others have no restrictions at all.

While federal laws do exist regarding firearms, there is no comprehensive federal law that specifically addresses high-capacity magazines. Similarly, local community guidelines may enforce certain regulations, but they often stem from the broader state laws. International treaties generally do not apply to the regulation of domestic firearms and their components, as this is typically left to individual states and their legislatures. Thus, state laws are the primary governing force for regulations on high-capacity magazines.
