Weapons Charges in California: Guns, Knives, and Prohibited Weapons

Overview of California's complex weapons laws, prohibited items, who can't possess firearms, and penalties for violations.

California has some of the strictest weapons laws in the nation. Even law-abiding gun owners can unknowingly violate complex regulations. From concealed carry rules to prohibited weapons bans, understanding these laws is essential for anyone who owns, carries, or encounters weapons in California.

Who Cannot Possess Firearms in California

Under California law, the following people are prohibited from owning or possessing firearms:

Convicted felons (any felony conviction)
Persons convicted of certain misdemeanors (domestic violence, assault, etc.)
Persons addicted to narcotics
Persons found mentally ill and dangerous
Persons under restraining/protective orders
Persons convicted of specified juvenile offenses
Persons under indictment for a felony
Fugitives from justice
Illegal aliens
Anyone dishonorably discharged from military

10-Year Firearms Ban for Certain Misdemeanors

California imposes a 10-year firearm ban for convictions of assault, battery, domestic violence, brandishing a weapon, and other specified misdemeanors—even without a felony conviction.

Prohibited Weapons in California

California prohibits possession of certain weapons regardless of criminal history. These include:

Prohibited Firearms

  • • Short-barreled rifles (under 16")
  • • Short-barreled shotguns (under 18")
  • • "Assault weapons" (as defined by CA law)
  • • .50 BMG rifles
  • • Machine guns
  • • Silencers/suppressors
  • • "Ghost guns" (unserialized)
  • • Multi-burst trigger activators

  • • Ballistic knives

  • • Cane swords
  • • Brass knuckles
  • • Nunchucks
  • • Shurikens (throwing stars)
  • • Billy clubs/blackjacks

California "Assault Weapon" Laws

California defines "assault weapons" through a combination of features tests and a specific list of prohibited models. Generally, centerfire rifles that accept detachable magazines AND have certain features are prohibited:

Features That Make a Rifle an "Assault Weapon"

Pistol grip
Thumbhole stock
Forward pistol grip
Folding or telescoping stock
Grenade/flare launcher
Flash suppressor
Threaded barrel (for flash suppressor)

The "Fixed Magazine" Workaround

Some gun owners use "fixed magazine" modifications to legally possess rifles with otherwise prohibited features. However, the law is complex and changes frequently. What's legal today may not be tomorrow. Always consult current regulations.

Concealed Carry Rules

California is a "may issue" state, meaning law enforcement has discretion to issue concealed carry permits. Recent Supreme Court decisions have changed the requirements, but California still has strict regulations:

CCW Permit Required

You cannot carry a concealed firearm in public without a valid CCW permit from your county sheriff or police chief

Good Cause (Changed)

After the Bruen decision, California can no longer require 'good cause' beyond self-defense, but extensive background checks remain

Training Required

Applicants must complete a firearms training course covering safety, laws, and shooting proficiency

Restricted Locations

Even with a CCW, carrying is prohibited in schools, government buildings, airports, and many other sensitive locations

Knife Laws

California knife laws are complex and depend on the type of knife and how it's carried:

Knife TypeOpen CarryConcealed Carry
Folding knife (any length)LegalLegal
Fixed blade knifeLegal (in sheath)Illegal (dirk/dagger)
Switchblade (under 2")LegalLegal
Switchblade (over 2")IllegalIllegal

Defense Strategies

Lack of Knowledge

You didn't know the weapon was there (e.g., someone else's gun in your car). Mere presence isn't enough—prosecution must prove you knew about the weapon.

Momentary Possession

You briefly possessed the weapon to dispose of it, prevent harm, or for other legitimate purpose without intent to exercise control.

Illegal Search

If police found the weapon through an illegal search (without warrant, consent, or exception), the evidence may be suppressed.

Rights Restored

Your firearm rights were restored through expungement, pardon, certificate of rehabilitation, or other legal mechanism.

Weapon Not Prohibited

The item doesn't actually meet California's legal definition of a prohibited weapon. Definitions are technical and specific.

Self-Defense/Necessity

In rare cases, temporarily possessing a weapon may be justified by immediate need to defend yourself or others.

Sentence Enhancements

Using a firearm during commission of another crime triggers significant sentence enhancements under PC 12022.53 ("10-20-Life"):

"10-20-Life" Enhancement

  • +10 years: Personal use of a firearm during felony
  • +20 years: Discharging a firearm during felony
  • +25 years to life: Causing death or great bodily injury with firearm

Key Takeaways

  • Many people are prohibited from firearm possession beyond just felons
  • California bans numerous weapons that are legal in other states
  • "Assault weapon" definitions are technical and based on specific features
  • CCW permits are available but highly regulated with many restricted locations
  • Using a firearm during a felony triggers severe sentence enhancements
