California Penal Code 417(a)(1) makes it a misdemeanor to draw or exhibit a deadly weapon other than a firearm in a rude, angry, or threatening manner in the presence of another person, or to use such a weapon unlawfully in a fight or quarrel. A conviction for brandishing a deadly weapon under PC 417(a)(1) carries a mandatory minimum of 30 days in county jail and a maximum of six months, plus a possible fine of up to $1,000.1California Legislative Information.

What the Prosecution Has to Prove
Four elements make the charge. You drew, exhibited, or used a deadly weapon that was not a firearm. Someone else was present. The display was rude, angry, or threatening, or the weapon was used during a fight or quarrel. And you were not acting in self-defense.1California Legislative Information. California Penal Code PEN 417
What’s missing from that list matters. The prosecution does not have to show you intended to hurt anyone, swung the weapon, or made contact. The charge turns on the display itself and the circumstances around it. Waving a knife in the middle of a shouting match can satisfy the statute even if you never moved toward the other person.
The “presence of another person” element is literal. Someone else has to be close enough to actually perceive the weapon. Handling a blade aggressively while alone, or in a room where no one can see you, does not violate this section. The law is concerned with the fear a display creates in a witness, so without a witness there is no offense here.
What Counts as a Deadly Weapon
Section 417(a)(1) covers deadly weapons other than firearms. Guns fall under 417(a)(2) with their own penalties. For this subsection, a deadly weapon is any object capable of causing death or serious bodily injury. Knives, machetes, and swords are the obvious examples, but the category reaches further.
Everyday objects qualify when they can inflict serious harm in the way they are used. A baseball bat, a heavy wrench, a glass bottle, or a sharpened screwdriver can all meet the definition. Courts look at the object’s physical characteristics and how it was wielded. The object does not have to be designed as a weapon; it just has to be dangerous as one.1California Legislative Information. California Penal Code PEN 417
Penalties for a 417(a)(1) Conviction
The offense is a misdemeanor with a mandatory floor of 30 days in county jail and a ceiling of six months.1California Legislative Information. California Penal Code PEN 4172California Legislative Information. California Penal Code PEN 19 The court can also impose a fine of up to $1,000, or both the fine and jail time.
Judges often add informal (summary) probation, typically running one to three years. Conditions commonly include staying out of further legal trouble and completing any ordered programs. Violating a condition can result in revocation and imposition of the jail term.
The 30-day minimum is what sets this charge apart from many other California misdemeanors. For most misdemeanors a judge can sentence someone to probation alone with no custody time. That option is not available here. Even a first-time offender with no record faces at least 30 days.
The Self-Defense Exception
The statute explicitly carves out self-defense. If you drew the weapon because you reasonably believed you or someone else faced an imminent threat of death or serious bodily harm, and the display was a proportional response, you have a complete defense.1California Legislative Information. California Penal Code PEN 417
Three conditions generally have to line up. The threat must be imminent, not something that happened earlier or might happen later. Your belief that you were in danger must be reasonable, not just sincere. And the response must be proportional to what you faced. Pulling a knife because someone yelled an insult will not qualify. Pulling one because a larger, aggressive person has cornered you and raised a fist is a different situation. The same framework applies to defending someone else.
How Brandishing Compares to Assault With a Deadly Weapon
Brandishing is sometimes confused with assault with a deadly weapon under Penal Code 245(a)(1), but they sit on different tiers. Assault with a deadly weapon requires the prosecutor to show you actually attempted to use force against someone with the weapon, not just that you displayed it. PC 245(a)(1) is a wobbler that can be charged as a misdemeanor (up to one year in county jail and a $10,000 fine) or a felony (two, three, or four years in state prison).3California Legislative Information. California Penal Code PEN 245 A brandishing conviction keeps the exposure in misdemeanor territory with a six-month maximum.
If a Firearm Was Involved
Brandishing a firearm falls under a different subsection and carries stiffer penalties. Displaying a concealed handgun or similar firearm in public in a rude, angry, or threatening way under Section 417(a)(2) carries a mandatory minimum of three months in county jail and a maximum of one year, with a fine that can reach $1,000. The firearm does not need to be loaded.1California Legislative Information. California Penal Code PEN 417
Expungement After the Case Ends
A 417(a)(1) conviction does not have to stay on your record permanently. Under Penal Code 1203.4, you can petition the court for a dismissal after completing probation and satisfying its conditions. If probation was not granted, you can petition under Section 1203.4a one year from the date of sentencing, provided you have completed your sentence and are not currently on probation or facing another charge.4California Legislative Information. California Penal Code Part 2 Title 8 Chapter 1 Section 1203.4
If the court grants the petition, it sets aside the conviction and dismisses the case, releasing you from most penalties and disabilities tied to the offense. The relief is meaningful but not absolute: an expunged conviction can still appear in certain background checks, particularly for law enforcement positions and some government jobs. Unpaid restitution alone cannot be grounds for denying the petition.
Consequences Beyond the Courtroom
The jail time and fine are the official penalties, but the ripple effects often matter more over the long run. A misdemeanor weapons conviction shows up on standard background checks and can complicate job applications, housing, and professional licensing. Many licensing boards require disclosure of any criminal conviction and evaluate whether it relates to the profession; weapons offenses tend to draw scrutiny even when the facts were minor.
For non-citizens, any weapons-related conviction deserves extra care. Whether a brandishing conviction triggers immigration consequences depends on individual circumstances, including your immigration status and criminal history. Weapons offenses can raise issues of deportability or inadmissibility depending on how federal immigration authorities classify the conviction. If you are not a U.S. citizen and facing a brandishing charge, talk to an immigration attorney before accepting any plea. The criminal penalties may be manageable; an unexpected immigration consequence may not be.
