Large-Capacity Magazines

Penal Code 32310 PC – Possession of Large-Capacity Gun Magazines

California Penal Code 32310 PC makes it a crime for someone to possess, sell, purchase, give away, import, transport, or manufacture large-capacity gun magazines, described as any ammunition-feeding device that can hold more than ten rounds.

However, this law has been fraught with controversy and legal challenges. For example, as recently as September 2023, a federal judge ruled banning large-capacity magazines was unconstitutional. Thus, while the law exists, the actual enforcement of this law is unclear.

Penal Code 32310 PC – Possession of Large-Capacity Magazines
PC 2310 prohibits possessing large-capacity gun magazines that can hold more than 10 rounds.

This law aims to reduce gun violence by restricting access to ammunition-feeding devices capable of holding more than ten rounds, but successful routine court challenges have created confusion. Currently, in California, possession, sale, manufacture, or importation of large-capacity magazines is prohibited by law.

Penal Code 32310 PC says, “(a) Except as provided by law… any person in this state who manufactures or causes to be manufactured, imports into the state, keeps for sale, or offers or exposes for sale, or who gives, lends, buys, or receives any large-capacity magazine is punishable by imprisonment in a county jail not exceeding one year or imprisonment under subdivision (h) of Section 1170.

(b) For purposes of this section, “manufacturing” includes both fabricating a magazine and assembling a magazine from a combination of parts, including, but not limited to, the body, spring, follower, and floor plate or end plate, to be a fully functioning large-capacity magazine.

(c) Except as provided law…  commencing July 1, 2017, any person in this state who possesses any large-capacity magazine, regardless of the date the magazine was acquired, is guilty of an infraction or misdemeanor punishable by a fine not to exceed $100 per large-capacity magazine, by imprisonment in a county jail not to exceed one year, or by both that fine and imprisonment.

(d) Any person who may not lawfully possess a large-capacity magazine commencing July 1, 2017, shall (1) Remove the large-capacity magazine from the state; (2) Sell the large-capacity magazine to a licensed firearms dealer; or (3) Surrender the large-capacity magazine to a law enforcement agency for destruction.”
