Hot off the press; the Ninth Circuit Court of Appeal just affirmed the federal district court’s summary judgment in favor of plaintiffs challenging California Government Code § 32310, which attempted to ban possession of large-capacity magazines; i.e., those that hold more than ten rounds of ammunition, ruling that the ban violated the Second Amendment. The case is Duncan v. Becerra (9th Cir. Aug. 14, 2020) __ F.3rd __ [2020 U.S.App. LEXIS 25836]. So you can take your large capacity magazines out of hiding now and publicly display and use them without concern.
