II. CAN I CONTINUE TO POSSESS THE MAGAZINES I LAWFULLY ACQUIRED?
YES! As of the date of this bulletin, California’s restrictions against “possession” have been unenforceable since June 29, 2017, when this same court issued a preliminary injunction preventing it from taking effect while the parties litigated the merits of the case.
III. CAN I USE THE MAGAZINES I LAWFULLY ACQUIRED AT A SHOOTING RANGE?
YES! For the same reasons above, California does not currently prohibit the “possession” of magazines capable of holding more than 10 rounds. Only activities involving the manufacture, importation, sale, transfer or receipt of such magazines are prohibited. The mere “use” of a magazine at a shooting range, for example, is not specifically prohibited. But BEWARE: the use of any “large-capacity” magazine in either a semiautomatic, centerfire rifle with a fixed magazine or a semiautomatic pistol with a fixed magazine could classify the firearm as an illegal “assault weapon” under California law.1
