California Gun Law Update: 3-in-30 Struck Down, Ammo Background Checks in Limbo

Hey friends—let’s catch up. California just had a couple of major legal rulings that could reshape California gun laws. If you’re following the Second Amendment in California, here’s the latest on the 3-in-30 ruling and the California ammunition background check ruling.

The 3-in-30 Ruling: One Firearm Every 30 Days? Not Anymore

On June 20, 2025, the Ninth Circuit Court of Appeals struck down California’s law that limited people to just one firearm purchase every 30 days. This so-called one-gun-a-month law was ruled unconstitutional under the Bruen standard, which requires firearm restrictions to align with historical tradition. For now, Californians are no longer stuck waiting weeks between purchases—though the state may appeal.

The Ammunition Background Check Ruling

Since 2019, California has required a background check every single time you buy ammunition. On July 24, 2025, a three-judge panel of the Ninth Circuit ruled the ammo background check law unconstitutional, saying it burdens lawful gun owners without a historical basis.

But here’s the catch: the ruling is on hold. California requested an en banc rehearing, so the California ammunition background check ruling won’t take effect until the full Ninth Circuit decides. For now, the checks continue.

Quick Recap

Issue	Ruling Outcome	Current Status
3-in-30 (one-gun-a-month law)	Struck down as unconstitutional (June 2025)	No longer enforceable (pending appeals)
California ammunition background check ruling	Struck down by 3-judge panel (July 2025)	Still in effect—paused while full Ninth Circuit reviews

Why This Matters: A Win for California Gun Owners

For those of us who lean left politically but still support the Second Amendment in California, these cases are a real win. The 3-in-30 ruling means the state can’t arbitrarily dictate how often you can buy a firearm. The California ammunition background check ruling acknowledges that requiring a background check every time you buy ammo unfairly burdens responsible gun owners.

This is a win for California gun owners because it shows the courts are beginning to rein in overly broad laws. It doesn’t erase all regulations, but it does mean lawmakers will have to be more precise and respectful of rights. For those of us building a pro-Second Amendment community in California, it’s a step forward.
