Traditional slingshots are legal to own in California. The state doesn’t require a permit, registration, or background check for the familiar Y-shaped, elastic-band kind, and adults can buy one at a sporting goods store without violating any state law. What gets people into trouble is a one-letter cousin called a slungshot, a handful of places where slingshots are off-limits, and the criminal statutes that kick in the moment a slingshot is used to hurt someone or damage property.
The Slingshot and Slungshot Distinction
California’s weapon laws turn on a distinction most people have never heard of. A traditional slingshot, with its forked frame and elastic bands, is not listed among the generally prohibited weapons in Penal Code 16590.1California Legislative Information. California Penal Code PEN 16590 You can keep one at home without a problem.
A slungshot is something else: a weighted striking weapon, typically a lead ball attached to a cord or flexible handle, meant to be swung at a person. California groups slungshots with billyclubs, blackjacks, sandbags, and saps under Penal Code 16590(m). Manufacturing, selling, or possessing one is punishable by up to a year in county jail, and Penal Code 22210 makes the offense a wobbler that prosecutors can charge as a felony when the circumstances warrant it.2California Legislative Information. California Penal Code PEN 22210
Who Can Buy One
There is no statewide permit, registration, waiting period, or licensing scheme for traditional slingshots. Any adult can buy one for recreation or use on private property.
Selling to minors is murkier than it might look. Penal Code 19910 makes it a misdemeanor to sell a “BB device” to a minor, and some retailers apply that rule to slingshots.3California Legislative Information. California Penal Code PEN 19910 The statute itself targets devices that fire metallic projectiles through air pressure, CO₂, or spring action, rather than naming elastic-powered slingshots. Whether a given slingshot qualifies depends on its design and the projectiles used with it. Many retailers require buyers to be 18 anyway, and some cities have their own age rules, so a parent buying one for a child should check the local municipal code.
Where You Cannot Take One
School Grounds
Penal Code 626.10 lists weapons banned on school campuses, including knives with blades over two-and-a-half inches, tasers, and instruments that expel metallic projectiles through air pressure, CO₂, or spring action.4California Legislative Information. California Penal Code PEN 626.10 Traditional elastic-band slingshots aren’t explicitly on that list. School administrators, however, have broad authority to confiscate anything they consider dangerous, and bringing a slingshot onto campus will produce discipline or a police call regardless of whether the specific criminal statute applies.
Federal Buildings
18 U.S.C. § 930 prohibits bringing firearms or “dangerous weapons” into federal facilities, defining a dangerous weapon broadly as any device “used for, or readily capable of, causing death or serious bodily injury.”5Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities Slingshots fit that description. Treat courthouses, Social Security offices, and other federal buildings as off-limits.
Airplanes
TSA does not allow slingshots in carry-on luggage; they have to go in checked bags.6Transportation Security Administration. Slingshots The officer at the checkpoint has the final call on any item.
City and County Parks
Local governments frequently regulate slingshots even when the state does not, and public parks are the most common place restrictions turn up. San Diego’s municipal code prohibits using, possessing, transporting, or carrying a slingshot in any city park or designated open space without specific authorization; violations range from infractions to misdemeanors depending on the circumstances.7San Diego Municipal Code. Chapter 6, Article 3 – Section 63.08 San Diego County parks apply a similar ban, listing slingshots alongside firearms, air guns, bows, crossbows, and paintball guns.8San Diego Parks and Recreation. San Diego County Code of Regulatory Ordinances – Section 41.117 Los Angeles and other large cities have their own rules on projectile devices, sometimes lumping slingshots with BB guns and air rifles or restricting discharge within city limits. Before using a slingshot in any public space, check the local code. When in doubt, keep it at home or on private land where you have permission.
When Legal Ownership Becomes a Crime
Owning a slingshot is one thing. Using one against people, cars, or property triggers charges that don’t depend on the slingshot itself being classified as a weapon.
Assault With a Deadly Weapon
Prosecutors can charge slingshot injuries under Penal Code 245(a)(1). Courts evaluate whether the object as used was capable of causing death or serious injury, and a slingshot firing a steel ball or marble at close range meets that standard. A conviction carries two, three, or four years in state prison, or up to a year in county jail, plus a fine of up to $10,000.9California Legislative Information. California Penal Code PEN 245 It’s also a strike offense under the Three Strikes Law.
Vandalism
Breaking windows, denting cars, or defacing property with a slingshot is vandalism under Penal Code 594. Damage of $400 or more can be charged as a felony carrying up to three years in county jail and a fine of up to $10,000; when damage reaches $10,000 or more, the maximum fine rises to $50,000.10California Legislative Information. California Penal Code PEN 594 Even under $400, misdemeanor vandalism can bring jail, probation, and a restitution order for all repairs.
Shooting at Vehicles
Vehicle Code 23110 makes it a misdemeanor to throw any object at a vehicle or its occupants on a highway. When the act is willful and done with intent to cause great bodily injury, it becomes a felony punishable by state prison.11California Legislative Information. California Vehicle Code VEH 23110 Launching a metal projectile at a windshield fits squarely in that felony range.
Hunting
California allows slingshots for taking certain nongame birds and mammals, but the rules are narrow. The Department of Fish and Wildlife controls which species qualify, and slingshots aren’t approved for game animals like deer or turkey. Hunters still need a valid license and must follow bag limits and season restrictions.
Federal law adds a serious trap. The Migratory Bird Treaty Act makes it illegal to pursue, hunt, capture, or kill any protected migratory bird species by any means unless federal regulations specifically allow it.12Office of the Law Revision Counsel. 16 USC Chapter 7, Subchapter II – Migratory Bird Treaty “By any means” includes slingshots. The list of protected migratory birds is far larger than most casual shooters realize, and it covers many species people think of as ordinary yard birds. Shooting one with a slingshot violates federal law no matter what California permits for nongame species.
