Let’s get into it.
What Is a Byrna Gun?
A Byrna gun is a CO2-powered launcher designed for less-lethal self-defense. Unlike traditional firearms, Byrna guns do not use bullets; instead, they fire chemical irritants, kinetic projectiles, or pepper balls that can incapacitate a threat without causing permanent harm.
Key Features of a Byrna Gun:
CO2-Powered Mechanism: Uses compressed CO2 cartridges to propel projectiles at high speeds.
Multiple Ammunition Types: Fires non-lethal rounds, including kinetic impact projectiles and chemical irritants like pepper balls.
Compact and Lightweight: Designed for easy carrying and rapid deployment in self-defense scenarios.
No Background Check Required: Unlike firearms, Byrna guns can be purchased without a federal background check.
Non-Firearm Classification: While powerful, Byrna guns are not considered firearms under federal law, though state laws may impose restrictions.
Are Byrna Guns Legal in California?
California law categorizes less-lethal weapons under California Penal Code 16780, meaning they are regulated but not classified as firearms.
This distinction is critical because, while Byrna guns do not require background checks or registration like traditional firearms, they are still subject to specific state laws.
For example:
Less-lethal weapons must comply with restrictions on chemical composition. Byrna guns cannot fire projectiles containing tear gas unless the owner has a special permit under California Penal Code 22810.
Modifying a Byrna gun is illegal. Increasing projectile velocity or altering the payload can result in felony charges.
Byrna guns are still covered under weapons laws. If used in a threatening manner, they may be treated similarly to firearms under California Penal Code 417, which criminalizes brandishing a weapon.
Using a Byrna gun in a crime leads to enhanced penalties. Under California Penal Code 12022, additional sentencing applies if a weapon is used in criminal activity.
Some areas prohibit all weapons, including Byrna guns. Locations such as schools, courthouses, and government buildings are covered under California Penal Code 626.9 and 171b, which ban weapons in sensitive areas.
So while Byrna guns are legal to own, misuse, improper carry, or unlawful modifications can still lead to serious legal consequences.
Can You Carry a Byrna Gun in Public in California?
Carrying a Byrna gun in public falls into gray legal territory depending on the circumstances:
Open carry is prohibited in most public spaces under California weapons laws.
Concealed carry is generally not permitted unless specific exemptions apply.
Byrna guns are banned in sensitive locations, including:
Schools and educational institutions (California Penal Code 626.9)
Government buildings
Airports and transportation hubs
Public gatherings or demonstrations
If used inappropriately, possession of a Byrna gun in public could result in misdemeanor or felony charges, depending on the context.
Where Can You Legally Use a Byrna Gun in California?
The state permits Byrna guns for home defense and private property use, but with restrictions:
Self-defense on private property is allowed under California’s Castle Doctrine (California Penal Code 198.5), which allows the use of force—including less-lethal weapons—if facing an immediate threat.
Using a Byrna gun in self-defense in a public setting requires legal justification under California’s self-defense laws (Penal Code 692), which state that force must be proportional to the threat faced.
Unjustified use of a Byrna gun, even in self-defense, could result in assault charges if authorities deem the response excessive or unwarranted.
Do You Need a Permit for a Byrna Gun in California?
No firearms permit is required to own a Byrna gun.
No background check is needed for purchase.
However, misuse or carrying a Byrna gun in restricted areas can result in criminal charges under California’s weapons laws.
Some local municipalities may have additional regulations, so checking county and city ordinances is recommended.
Byrna Gun vs. Firearms: What’s the Difference?
Byrna guns do not require background checks like traditional firearms.
They are considered non-lethal weapons, but still subject to state regulations.
Byrna guns do not require registration, unlike traditional firearms.
Misuse of a Byrna gun can lead to legal consequences similar to firearm misuse.
How Does a Byrna Gun Work?
When fired, a Byrna gun releases a high-pressure burst of CO2, propelling the selected ammunition towards the target.
The kinetic impact rounds are designed to deliver a painful but non-lethal force, while the chemical irritant projectiles release a debilitating cloud that can cause temporary blindness, breathing difficulties, and intense irritation—providing valuable seconds to escape danger.
Who Uses Byrna Guns?
Civilians: Many individuals use Byrna guns for home defense and personal protection.
Law Enforcement: Some agencies deploy Byrna guns for crowd control and non-lethal enforcement.
Security Personnel: Used by private security firms to subdue threats without lethal force.
Outdoor Enthusiasts: Campers and hikers may carry Byrna guns for protection against aggressive wildlife.
Byrna guns offer a legal self-defense option in California, but they are not without restrictions. While owning and using a Byrna gun at home is permitted, carrying it in public may be subject to legal penalties. Know the law. Stay within the limits. Be prepared.
