The long-running Duncan v. Bonta case has reached a critical turning point. After nearly a decade of legal battles, the Supreme Court of the United States has officially set a conference date for November 21st, marking what could be a historic decision for gun owners across California and the nation.

This pivotal case challenges California’s ban on magazines holding more than 10 rounds, often referred to as the state’s standard capacity magazine ban. The case has journeyed through every level of the judicial system — from the district court to the Ninth Circuit, up to the Supreme Court, and back again after the Bruen decision reshaped the Second Amendment landscape.

District Judge Roger Benitez has twice ruled the ban unconstitutional, citing that it violates the rights of law-abiding citizens under the Second Amendment. Despite that, enforcement remains on hold under an injunction, preventing California from enforcing the ban — for now.

On November 21st, the Justices will decide whether to accept or deny the case. If the Supreme Court refuses to hear it, the lower court ruling upholding the ban will stand — effectively outlawing all magazines over 10 rounds in California. This outcome would impact an estimated one million-plus magazines purchased during the state’s brief “Freedom Week.”

If the Court accepts the case, it could become the most significant Second Amendment showdown since NYSRPA v. Bruen, with nationwide implications for magazine capacity laws.

Unlike other 2A challenges, Duncan v. Bonta is fully developed, with a complete record ready for review. Advocates argue it represents the best opportunity yet for the Supreme Court to clarify limits on state restrictions regarding arms and capacity.

Though the Court has already taken up two Second Amendment cases this term, supporters believe Duncan’s clean record and broad impact make it too important to ignore.
