A charge under California Penal Code 245(b) for assault with a semi-automatic firearm is a straight felony punishable by three, six, or nine years in state prison, plus a possible fine of up to $10,000, a permanent strike on your record, and a lifetime ban on owning firearms.1California Legislative Information. California Penal Code PEN 245 – Assault with Deadly Weapon The offense sits between ordinary assault with a firearm under 245(a)(2) and the heavier penalties for assault with a machine gun or assault weapon under 245(a)(3), and the mechanical classification of the weapon is what drives it into this middle tier.
The Prison Term and Fine
PC 245(b) has no misdemeanor alternative. The judge picks one of three terms under California’s triad system: three years (low), six years (middle), or nine years (upper).1California Legislative Information. California Penal Code PEN 245 – Assault with Deadly Weapon The statute specifies state prison, so this offense is not eligible for county jail custody under realignment.
The subsection itself doesn’t list a specific fine. The fine authority instead comes from Penal Code 672, which allows courts to impose up to $10,000 for any felony where no fine is otherwise prescribed.2California Legislative Information. California Penal Code PEN 672 Restitution to the victim for medical expenses and other losses is separate, and both the fine and the restitution order remain enforceable after release.
Judges weigh prior record, the number of victims, and the recklessness of the conduct when choosing among the three terms. A first-time defendant who pointed but never fired in a brief confrontation has a stronger argument for the low term. Multiple rounds fired in a crowded location pushes toward the upper end.
What the Prosecution Has to Prove
To convict, the prosecution must establish four elements beyond a reasonable doubt:
- An act with a semi-automatic firearm that, by its nature, would probably result in force being applied to another person. Actual contact or injury isn’t required. Pointing a loaded weapon during a confrontation can be enough.
- Willful conduct. The physical act was intentional. The prosecution doesn’t have to prove you meant to injure anyone or break the law, only that the act itself was on purpose rather than accidental.
- Awareness of the danger, measured objectively. A reasonable person in the same position would have realized the act could result in force being applied to someone. Your personal read of the situation isn’t the test.
- The weapon was semi-automatic. It fires one round per trigger pull and automatically chambers the next round using energy from the fired cartridge.
That last element is the one that separates 245(b) from its neighbors. If the weapon was a revolver or another non-semi-automatic firearm, the charge drops to 245(a)(2). If it was a machine gun or a designated assault weapon, the charge climbs to 245(a)(3), which carries four, eight, or twelve years.1California Legislative Information. California Penal Code PEN 245 – Assault with Deadly Weapon
Probation Is Presumptively Denied
Felony probation instead of prison is theoretically available but rare here. Penal Code 1203(e)(2) says probation “shall not be granted” to anyone who used a deadly weapon on another person during the offense unless the court finds an “unusual case” where the interests of justice require it.3California Legislative Information. California Penal Code PEN 1203 Assault with a semi-automatic firearm fits squarely inside that restriction. In practice, courts grant probation on a 245(b) only in genuinely exceptional situations: minimal conduct, a very young defendant, or unusually strong mitigation.
Enhancements That Stack on Top
The base term is not the ceiling. If the assault caused serious physical harm, Penal Code 12022.7(a) adds three consecutive years for personally inflicting “great bodily injury,” meaning a significant or substantial physical injury.4California Legislative Information. California Penal Code PEN 12022.7 – Sentence Enhancements Broken bones, gunshot wounds requiring surgery, and deep lacerations typically qualify. Bruises and small cuts don’t.
Consecutive is the operative word. The enhancement doesn’t run at the same time as the base sentence. A defendant who receives the nine-year upper term plus the standard three-year GBI enhancement is looking at twelve years. Higher GBI enhancements apply when the victim suffers permanent paralysis or a coma from brain injury (five years), is 70 or older (five years), is a child under five (four, five, or six years), or when the assault occurs in domestic violence circumstances (three, four, or five years).4California Legislative Information. California Penal Code PEN 12022.7 – Sentence Enhancements
One enhancement that does not stack onto 245(b) is the personal firearm use enhancement under Penal Code 12022.5. That statute normally adds three, four, or ten years for personally using a firearm during a felony, but it excludes offenses where firearm use is already an element of the crime.5California Legislative Information. California Penal Code PEN 12022.5 Semi-automatic firearm use is the defining element of 245(b), so prosecutors cannot add this one on top.
A Strike, and Possibly the 85% Rule
A 245(b) conviction is a strike. Assault with a semi-automatic firearm is listed by name as a serious felony under Penal Code 1192.7(c)(31).6California Legislative Information. California Penal Code PEN 1192.7 If you’re later convicted of any new felony, the Three Strikes Law doubles the base sentence for that new offense, and total good-conduct credits on the new case are capped at one-fifth of the sentence.7California Legislative Information. California Penal Code PEN 667 A third strike for a serious or violent felony can trigger 25 years to life. The strike is permanent.
Whether 245(b) also counts as a violent felony under Penal Code 667.5(c) depends on what else the jury finds. The violent felony list does not name 245(b) directly. It does, at 667.5(c)(8), sweep in any felony where the defendant personally inflicts great bodily injury that has been charged and proved under 12022.7.8California Legislative Information. California Penal Code PEN 667.5 When a GBI finding attaches, the offense becomes a violent felony and Penal Code 2933.1 kicks in: worktime credits are capped at 15 percent, meaning at least 85 percent of the sentence must be served before release.9California Legislative Information. California Penal Code PEN 2933.1 Without the GBI finding, the offense is still a strike, but the 85 percent minimum may not apply.
Defenses That Fit This Charge
The prosecution doesn’t have to prove you intended to hurt anyone, so effective defenses target the other elements: willfulness, the objective reasonableness of the danger, and the weapon itself. Justification defenses are also available.
Self-Defense or Defense of Others
California allows the use of force, including deadly force, when a person reasonably believes it is necessary to prevent imminent death or great bodily injury to themselves or someone else. The response has to be proportional to the threat. Under Penal Code 198.5, a person who uses potentially deadly force inside their own home against someone who unlawfully and forcibly entered is presumed to have acted from a reasonable fear of imminent harm.10California Legislative Information. California Penal Code PEN 198.5 Outside the home, there’s no duty to retreat, but the reasonableness of the belief and the proportionality of the response face closer scrutiny.
Accident or Lack of Willfulness
If the act was genuinely accidental, it fails the willfulness element. A firearm that discharged during a stumble or while being handled for a non-threatening purpose can support this defense. Coercion is a related avenue: if you acted under an immediate threat of harm from a third party, the willfulness element may fail.
The Weapon Wasn’t Actually Semi-Automatic
Since the semi-automatic classification is what elevates the charge, challenging that classification is one of the most valuable defense moves. If ballistic analysis is inconclusive or the weapon was never recovered, the prosecution may not be able to prove this element. Winning on this point doesn’t produce an acquittal, but it can reduce the charge to 245(a)(2), which carries two, three, or four years and can be filed as a misdemeanor.1California Legislative Information.

Consequences That Outlast the Sentence
Firearm Ban for Life
California Penal Code 29800 prohibits anyone convicted of a felony from owning, purchasing, receiving, or possessing a firearm.11California Legislative Information. California Penal Code PEN 29800 Violating that ban is a separate felony. Federal law imposes a parallel prohibition under 18 U.S.C. ยง 922(g)(1), barring anyone convicted of a crime punishable by more than one year of imprisonment from possessing any firearm or ammunition.12Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The federal ban applies nationwide and follows you into states with more permissive firearm rules.
Immigration
For non-citizens, the consequences are severe. Federal immigration law treats a “crime of violence” with a potential sentence of at least one year as an aggravated felony under INA Section 101(a)(43)(F).13Legal Information Institute. 8 USC 1101(a)(43) – Aggravated Felony Assault with a semi-automatic firearm fits that definition. An aggravated felony conviction triggers mandatory detention during removal proceedings, bars almost all forms of relief from deportation (including asylum and cancellation of removal), and creates permanent inadmissibility. Lawful permanent residents with decades in the country face removal with essentially no path back.
Employment and Licensing
A violent felony conviction creates barriers in fields that require background checks, including healthcare, education, finance, and law enforcement. Professional licensing boards weigh felony convictions when evaluating applications, especially when the offense involves violence. Assault with a semi-automatic firearm is the kind of offense licensing agencies are most likely to flag as directly related to fitness for practice.
How 245(b) Compares to Related Charges
Understanding the neighboring subsections helps make sense of why prosecutors chose 245(b) and what alternatives might come up in plea talks:
- 245(a)(1) covers assault with a deadly weapon other than a firearm (knife, bat, car). Wobbler: up to one year in county jail as a misdemeanor, or two, three, or four years in state prison as a felony, with fines up to $10,000.
- 245(a)(2) covers assault with any firearm, including revolvers and other non-semi-automatic weapons. Also a wobbler, with felony penalties of two, three, or four years. This is the most common lesser charge when the semi-automatic classification can’t be proved.
- 245(a)(3) covers assault with a machine gun or assault weapon. Four, eight, or twelve years in state prison.
- 245(d)(2) covers assault on a peace officer or firefighter with a semi-automatic firearm when the officer is known to be performing their duties. Five, seven, or nine years.
The gap between 245(a)(2) and 245(b) is what makes weapon identification so consequential. Standard firearm assault can be filed as a misdemeanor. 245(b) is always a felony with a minimum three-year prison term.1California Legislative Information.
