Prohibited Weapons in Los Angeles
The Second Amendment of the U.S. Constitution grants American citizens the right to bear arms. This means U.S. citizens can possess, own, purchase, and use firearms (as well as certain other weapons). However, California stringently restricts such weapons that a person can own, purchase, or possess. Some weapons are entirely prohibited under the state’s laws.

Definitions: “Dangerous Weapons” and “Generally Prohibited Weapons”
On the 1st of January 2012, the term “dangerous weapons” under P.C. § 12020 was renamed “generally prohibited weapons” (now P.C. § 16590), and each weapon was ascribed its own individual Penal Code section, as reflected above.
See “Dangerous Weapons” Defined (California Penal Code section 12020); and
“Generally Prohibited Weapons” Defined (California Penal Code section 16590).
Illegal Activities Concerning Prohibited Weapons
P.C. § 16950 bars you from owning, possessing, manufacturing, giving out, lending, selling, offering for sale, or importing any “prohibited weapons” as defined therein.
But before the court or jury finds you guilty of violating P.C. § 16590, the prosecuting attorney must prove the following elements beyond any reasonable doubt:
- You possessed, owned, manufactured, caused the manufacture of, sold, kept with intent to sell, exposed/offered to sell, imported, lent, gave, received, or bought a device deemed to be a prohibited weapon;
- You knew you possessed, imported into the state, manufactured, caused the manufacture of, exposed/offered to sell, kept intending to sell, received, bought, lent, or gave the weapon; and
- You knew the item was a prohibited weapon meant for illegal purposes or one that may be utilized for illegal purposes.
The prosecuting attorney does not have to demonstrate that you intended to utilize the device as a weapon for illegal purposes. They only must show that you were aware the object could be used in that manner.
Additionally, the prosecution does not have to prove that the device is in working condition to be utilized as a weapon. And if accused of selling, manufacturing to sell, or possessing to sell a prohibited weapon, the prosecuting attorney must also show that you aimed to sell it.
As regards possession, there are two types — constructive and actual possession. Under actual possession, you hold or can immediately access the prohibited weapon. This includes a scenario where the weapon is on your person, for example, in your shirt’s pocket or something on you, such as your backpack, briefcase, or purse.
Constructive possession concerns a situation where you cannot immediately access the prohibited weapon but have control over it or are entitled to assume its control. For example, having the weapon in your bedside drawer or car trunk.
Certain weapons, situations, and people are exempt from being charged under California Penal Code section 16590.
- When forensic laboratories possess prohibited weapons.
- When you are turning a prohibited weapon over to the police.
- When unloaded weapons are used in television, video, and movie productions — P.C. § 17720 permits people to use prohibited weapons to film a television program, motion picture, video production, or theatrical production, but only after a valid permit is obtained.
See Firearms Exemption for Employee or Agent of Television Program, Motion Picture, Video Production, or Theatrical Production (California Penal Code section 17720).
If you are at least 21, you can acquire an Entertainment Firearms Permit from the California Department of Justice.
The permit allows you to possess guns for use only as props in a television, theatrical, video, motion picture, or any other entertainment event or production.
- When museums, libraries, and historical societies possess prohibited weapons.
- When a seller/collector of curios or antiques possesses ammunition or a relic firearm.
- When schools that teach martial arts possesses nunchakus, shurikens, batons, etc.
- When prohibited weapons are possessed by or transferred/sold to a law enforcement agency.
The Consequences of Violating Penal Code section 16590
A P.C. § 16590 violation is considered a “Wobbler” (California Penal Code section 17(b)). A wobbler is an offense that the prosecuting attorney can try as a felony or misdemeanor based on the defendant’s criminal history and the circumstances surrounding the charges.
If pronounced guilty of a misdemeanor, the court could fine you up to $1,000 or sentence you to jail for a period not exceeding 12 months. If facing a felony conviction, the judge could fine you not more than $10,000 or sentence you to a prison term of 16 months, two or three years.
Immigration Consequences of Violation PC 16590
Being convicted of a P.C. § 16590 violation will not negatively affect your immigration status. Non-citizens found guilty of an offense can sometimes be labeled inadmissible or be deported. Convictions that can lead to the deportation or inadmissibility of an immigrant are those considered to be aggravated felonies and crimes of moral turpitude.
California courts have established that a P.C. § 16590 violation does not fall under aggravated felonies or crimes of moral turpitude. Therefore, a convicted immigrant will not be deported or classified as inadmissible.
A P.C. § 16590 Violation’s Effect on Gun Rights
Being convicted under P.C. § 16590 can negatively affect your firearm rights. California law provides that anyone convicted of a felony is prohibited from possessing, owning, and purchasing a firearm.
Note that violating P.C. § 16590 can be prosecuted as a felony or misdemeanor. Thus, if you are accused of a felony activity involving a prohibited weapon and are ultimately convicted, you will forfeit your firearm rights.
Defending Against P.C. § 16590 Violation Charges
If charged with manufacturing, selling, or possessing a prohibited weapon, or violating P.C. § 16590 in some other way, an experienced gun and weapon offenses lawyer may be capable of arguing several defenses for you. These defenses include:
Illegal Search and Seizure
Most charges under P.C. § 16590 arise after the police stop a person and conduct an investigation, followed by a search. However, know that the police cannot search your person or property, or seize your property, in the absence of a judge-issued search warrant.
They must have a valid reason (probable cause) to search you or seize your property if they lack a search warrant. Should the police collect evidence after an illegal search and seizure, the evidence can be struck from the case, meaning the charges may be reduced or even dismissed.
See Motion to Dismiss (California Penal Code section 995);
Motion to Suppress Evidence (California Penal Code section 1538.5); and
Fourth Amendment to the U.S. Constitution.
You Did Not Know the Weapon was Prohibited or Could be Used as a Prohibited Weapon for Illegal Purposes
The prosecutor must prove you were aware the item you possessed, sold, or manufactured was a prohibited weapon or could be used as a weapon for illegal purposes. If you were unaware the object was a prohibited weapon or could be utilized as such, the judge or jury should not find you guilty of this offense.
This defense protects innocent, legitimate weapon transporters, who do not know anything about the cargo they are moving, are never told thereof, and do not have any reason to believe it is a prohibited weapon. However, being informed that the object is a prohibited weapon but not seeing it since it is concealed in transport will not act as a legal defense.
If accused of possessing a prohibited weapon, the prosecuting attorney must demonstrate that you knew you had actual or constructive possession of the weapon. For example, someone may have placed the weapon in your backpack, purse, or even your trouser pocket, and you did not notice. If you can prove you were unaware you had the weapon, the judge or jury should not find you guilty of a P.C. §16590 violation.
The Item was Not a Prohibited Weapon
The prohibited weapons list under P.C. § 16590 is fairly straightforward. Therefore, if the item you sold, manufactured, or possessed does not have the features of any of the prohibited weapons mentioned above, the judge or jury should not convict you of this offense.
You are Authorized to Handle Prohibited Weapons, or You are an Exempt Party
Some weapons listed under California Penal Code section 16590 can be manufactured, possessed, or sold under strict conditions. For example, although nunchakus are prohibited weapons, P.C. § 22015 allows schools that teach self-defense or martial arts to possess them.
See Prohibited Weapons Exemption for Martial Arts or Self-Defense Instructor (California Penal Code section 22015).
The same Penal Code section also allows the sale and manufacture of nunchakus to these schools. You also cannot be convicted of a P.C. § 16590 violation if you fall under any of the exempt groups of people mentioned above.
The prosecution must prove all the elements of P.C. § 16590 violation beyond any reasonable doubt. If it fails to prove even a single element to the law’s satisfaction, that would be grounds to argue inadequate evidence as a defense.
Also, if your attorney can successfully poke holes in the prosecution’s evidence, it would cast doubt in the judge or jury’s minds, which could lead to a charge dismissal.
The prosecution team’s role is to present evidence that you are undoubtedly guilty of the charges against you. It should convince the jury and judge beyond any reasonable doubt to find you guilty only based on the available evidence.
The prosecuting attorney should never try to influence the judge or jury to convict you unfairly. That would be prosecutorial misconduct. If your lawyer can prove any prosecutorial misconduct, the judge can dismiss the charges against you or lower your sentence.
In a situation where you were accused of possessing a prohibited weapon, you could argue momentary possession as a defense. Briefly possessing a prohibited weapon is not an offense. It could be that you had the weapon temporarily with the intent to turn it over to the authorities.
Police misconduct during arrest or investigation into your case may result in a dismissal of the charges against you.
Police misconduct may include:
- Discovering the prohibited weapon in an illegal search.
- Planting or fabricating evidence.
- Coercing a confession.
- Any other conduct that violates your constitutional rights.
You can argue the entrapment defense if you establish that the police lured, coerced, or convinced you into illegal conduct. The state’s criminal law presumes that any ordinary, sensible party will resist committing an offense absent extraordinary circumstances.
For example, suppose you run an antique store. An undercover police officer requests that you give them a belt-buckle knife. You refuse, but they insist for several days until you finally agree to their request so that they can stop standing in the way of your business. The court should not convict you of P.C. § 16590 violation since you did not willingly participate in the offense.
But if the police officer asks you for the belt-buckle knife and you do not have it but offer to find one for them, you have initiated the offense, thereby rendering yu culpable
Carrying a Prohibited Weapon to Scare Attackers Away Does Not Qualify as a Defense
Whereas your intention could be to display the weapon solely for self-defense, P.C. § 16590's purpose is to safeguard people from coercion or fear that might be caused by seeing that kind of weapon.
For example, a robber enters a convenience store carrying an inoperable sawed-off shotgun. The clerk at the counter is unaware the robber cannot fire the shotgun, so they still empty the register upon the robber’s order. Reducing this kind of coercion and fear is one reason these weapons are banned.

Personal Use of a Firearm During a Felony (California Penal Code section 12022.5).
Conviction Record Expungement
You can expunge your P.C. § 16590 conviction. An expungement is possible, provided you successfully serve your jail sentence and/or probation term, whichever is applicable. A conviction record expungement is beneficial because it eliminates most of the challenges of a conviction.
See Expungement (California Penal Code section 1203.4).

Early Termination of Probation (California Penal Code section 1203.3).
Crimes Related to P.C. section 16590 Violation
Three offenses are related to unlawful acts with prohibited weapons because they share various elements. As a result, the prosecutor can charge you with these crimes alongside or instead of a P.C. § 16590 violation. The crimes are:
Publicly Carrying an Unloaded Gun (California Penal Code section 26350)
P.C. § 26350 is the state’s law criminalizing the carrying of an unloaded gun openly and doing so publicly. Note that carrying an unloaded firearm in a private residence is legal.
Violating P.C. § 26350 is considered a misdemeanor. A conviction will subject you to a fine not exceeding one thousand dollars and custody in jail for a maximum of one year.
You could be subject to a fine and jail term if you had also been carrying unexpended, dischargeable ammunition and were not the legal owner of the firearm. Additionally, the above charge applies to every unloaded firearm you carry.
See also “Carrying Loaded Firearm: Not Registered Owner -- Pen. Code § 25850(c)(6)”: CALCRIM Number 2545; and
“Carrying Concealed Firearm: Not Registered Owner and Weapon Loaded -- Pen. Code § 25400(c)(6)”: CALCRIM Number 2546.
Publicly Carrying a Loaded Firearm (California Penal Code section 25850(a))
P.C. § 25850 is the state’s law that criminalizes carrying a loaded gun in a car or in public. Remember that you will be convicted of violating this statute while doing so with any gun. Additionally, the weapon needs not be prohibited per P.C. § 16590.
A simple P.C. § 25850 violation is deemed a misdemeanor. The consequences include up to one thousand dollars in fines and custody in jail for a period not exceeding one year. However, certain aggravating circumstances can cause a P.C. § 25850 violation to be charged as either a straight felony or a wobbler. You will also be ordered to serve a jail term of at least three months if you have particular priors.
See also Carrying an Exposed and Unloaded Handgun in a Public Place or in a Vehicle (California Penal Code section 26350); and
“Carrying Loaded Firearm -- Pen. Code § 25850(a)”: CALCRIM Number 2530).
Brandishing a Weapon (California Penal Code section 417(a)(1)&(2))
P.C. § 417 is the state’s law that describes the criminal offense of brandishing a weapon. This crime is defined as exhibiting or drawing a firearm or deadly weapon, or using any deadly weapon in a fight. This law does not only apply to firearms. It also applies to objects that are deemed deadly weapons.
Most P.C. § 417 violations are misdemeanors. The consequences upon a conviction are a county jail sentence for a period not exceeding one year.
