See our Multiple Purchases or Sales of Firearms policy summary for a comprehensive discussion of this issue.
California law prohibits the purchase of more than one handgun within any 30-day period. Also, licensed firearms dealers may not deliver a handgun to anyone following notification from the California Department of Justice that the purchaser has applied to acquire another handgun within the preceding 30-day period. These restrictions do not apply to firearm transactions between private parties, even when those transactions are processed as required through a licensed dealer.
Firearms dealers are required to post conspicuously in their licensed premises a warning, in block letters at least one inch in height, that notifies potential purchasers of the prohibitions on applications to purchase and dealer delivery of multiple handguns within any 30-day period.
