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.
Under California law, the following people are prohibited from owning or possessing firearms:
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.
| Offense | Code Section | Classification | Penalty |
|---|---|---|---|
| Felon in possession | PC 29800 | Felony | 16 mo, 2, or 3 years |
| Carrying concealed firearm | PC 25400 | Wobbler | Up to 1 yr or 16 mo-3 yr |
| Carrying loaded firearm | PC 25850 | Wobbler | Up to 1 yr or 16 mo-3 yr |
| Brandishing a weapon | PC 417 | Misdemeanor | Up to 1 year jail |
| Negligent discharge | PC 246.3 | Wobbler | Up to 1 yr or 16 mo-3 yr |
California prohibits possession of certain weapons regardless of criminal history. These include:
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:
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.
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:
You cannot carry a concealed firearm in public without a valid CCW permit from your county sheriff or police chief
After the Bruen decision, California can no longer require 'good cause' beyond self-defense, but extensive background checks remain
Applicants must complete a firearms training course covering safety, laws, and shooting proficiency
Even with a CCW, carrying is prohibited in schools, government buildings, airports, and many other sensitive locations
California knife laws are complex and depend on the type of knife and how it's carried:
| Knife Type | Open Carry | Concealed Carry |
|---|---|---|
| Folding knife (any length) | Legal | Legal |
| Fixed blade knife | Legal (in sheath) | Illegal (dirk/dagger) |
| Switchblade (under 2") | Legal | Legal |
| Switchblade (over 2") | Illegal | Illegal |
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.
You briefly possessed the weapon to dispose of it, prevent harm, or for other legitimate purpose without intent to exercise control.
If police found the weapon through an illegal search (without warrant, consent, or exception), the evidence may be suppressed.
Your firearm rights were restored through expungement, pardon, certificate of rehabilitation, or other legal mechanism.
The item doesn't actually meet California's legal definition of a prohibited weapon. Definitions are technical and specific.
In rare cases, temporarily possessing a weapon may be justified by immediate need to defend yourself or others.
Using a firearm during commission of another crime triggers significant sentence enhancements under PC 12022.53 ("10-20-Life"):
