California Penal Code 12020 PC - Possession of Certain Weapons and Explosives
Under California Penal Code 12020 PC, it was historically illegal to manufacture, import, sell, give, or possess certain concealed, dangerous, or illegal weapons, firearms, and explosives.
While PC 12020 served for decades as California's blanket statute criminalizing dangerous weapons, the California Legislature reorganized the statute into Penal Code Sections 16590 PC et seq. (the Deadly Weapons Recodification Act).
Despite this statutory renumbering, prosecutors and courts continue to enforce the exact same legal standards, criminalizing items such as cane swords, metal knuckles, short-barreled shotguns, zip guns, and concealed explosives.
Understanding the statutory elements, weapon categories, felony penalties, and legal defense strategies under California's prohibited weapons framework is critical if you or a loved one faces criminal charges.
What Is the Statutory Language of PC 12020?
California Penal Code Section 12020 PC establishes the general prohibitions against manufacturing, importing, possessing, or transferring designated dangerous weapons and explosives.

What Are Key Statutory Definitions Under California Prohibited Weapons Laws?
To understand how California courts evaluate weapons violations, it is necessary to examine key statutory definitions established under state law and jury instructions:
1. Metal Knuckles (Penal Code 21810 PC / Formerly PC 12020)
Metal knuckles are defined as any device or instrument made wholly or partially of metal, plastic, or hard material designed to be worn on or held by the hand or fingers to increase the force of a punch or strike.
2. Short-Barreled Shotgun or Rifle (Penal Code 33215 PC / Formerly PC 12020)
A short-barreled shotgun has a barrel length of less than 18 inches or an overall length of less than 26 inches. A short-barreled rifle has a barrel length of less than 16 inches or an overall length of less than 26 inches.
3. Concealed Explosive Substance
A concealed explosive substance includes any dynamite, nitroglycerin, black powder, or blasting cap carried surreptitiously on a person's body or inside clothing, bags, or personal belongings without legal permit or authorization.
What Must Prosecutors Prove to Convict You of Possessing Prohibited Weapons?
To secure a conviction for possessing or manufacturing prohibited weapons under California's statutory weapons framework, prosecutors must prove the following elements of the crime beyond a reasonable doubt:
-
Prohibited Action: The defendant manufactured, imported, kept for sale, offered, gave, lent, or possessed a designated prohibited weapon or explosive.
-
Knowledge of Presence and Character: The defendant knew they possessed the object and was aware of the item's dangerous characteristics or physical nature (e.g., knew the object was a blade concealed inside a cane).
-
Control Over the Item: The defendant exercised actual physical control over the weapon or constructive control (control through dominion over the space where it was located).
What Are the Penalties for Possessing Prohibited Weapons in California?
Most offenses under California's prohibited weapons framework are wobblers, meaning prosecutors can charge them as either a misdemeanor or a felony depending on the defendant's criminal history and case circumstances.

What Are Common Legal Defense Strategies for Prohibited Weapons Charges?
An experienced California criminal defense attorney can employ several strategic defense arguments to challenge weapons charges:
-
Lack of Knowledge or Awareness: Demonstrating that you were completely unaware the prohibited item was in your possession or vehicle (e.g., a passenger left metal knuckles under your car seat without your knowledge).
-
Item Does Not Meet Statutory Definition: Proving through expert examination that the seized object does not meet the exact legal criteria for a prohibited weapon (e.g., showing a blade length or barrel dimension falls within legal limits).
-
Unlawful Search and Seizure (PC 1538.5): Filing a motion to suppress evidence if law enforcement officers discovered the weapon during an illegal traffic stop, unconstitutional pat-down, or warrantless search.
-
Curio, Relic, or Antique Exemption: Establishing that the item qualifies under statutory exemptions for licensed antique collectors, museum displays, or authorized theatrical props.
-
Momentary Possession for Disposal: Showing that you only took temporary possession of the item to dispose of it or hand it over to law enforcement.
Hypothetical Example of a Prohibited Weapons Case
To better understand how California prohibited weapons laws apply in practice, consider the following scenario:
Scenario: Brian purchases an antique walking cane at a flea market to add to his home collection. Unbeknownst to Brian, pressing a hidden latch on the handle releases a concealed 12-inch steel blade inside the shaft (a "leaded cane" or "sword cane"). During a routine traffic stop for a broken taillight, an officer notices the cane on the passenger seat, inspects it, discovers the blade, and arrests Brian for felony possession of a concealed weapon under California weapons law.
Legal Outcome: Brian hires a criminal defense attorney who gathers purchase receipts, antique catalog listings, and witness testimony proving Brian purchased the item purely as a decorative antique and had zero knowledge that it contained a concealed blade. Because prosecutors cannot establish the mandatory element of knowing possession of a dangerous weapon, all felony charges are dismissed.

Frequently Asked Questions (FAQs)
Is Penal Code 12020 PC still an active law in California?
The provisions of former PC 12020 were reorganized in 2012 into Penal Code Sections 16590 PC et seq. under the California Deadly Weapons Recodification Act. However, the legal definitions, prohibitions, and penalties remain identical, and many court documents still reference PC 12020.
Can I be arrested for possessing a weapon I bought legally in another state?
Yes. Bringing a weapon into California that is illegal under California law—such as metal knuckles, nunchaku, or short-barreled shotguns—violates state law even if the item was legally purchased in another state.
Are nunchaku or martial arts weapons illegal in California?
California law generally prohibits possessing nunchaku in public or manufacturing them. However, California provides limited statutory exceptions for authorized martial arts schools and academies operating in designated locations.
What is the difference between a misdemeanor and a felony weapons charge?
Misdemeanor convictions carry up to one year in county jail and lighter fines. Felony convictions carry potential state prison or county jail terms of 16 months, 2 years, or 3 years, along with the permanent loss of firearm ownership rights.
Can police search my car trunk for weapons during a routine traffic stop?
No. Officers cannot search your trunk without a valid search warrant, explicit voluntary consent, or clear probable cause to believe the trunk contains evidence of a crime or contraband. Evidence seized during an illegal search can be suppressed under PC 1538.5.
