A conviction under California Penal Code 245(b) carries penalties of three, six, or nine years in state prison, and because assault with a semiautomatic firearm is a straight felony with no misdemeanor or county jail alternative, prison is the only sentencing destination the statute allows.1California Legislative Information. California Penal Code PEN 245 – Assault With Deadly Weapon The sentence is only the start. The offense is both a serious and a violent felony, which means a strike, limited custody credits, a lifetime firearms ban, and, for non-citizens, near-certain deportation.
The Prison Term
The statute sets a sentencing triad of three, six, or nine years. Six years is the presumptive middle term. The judge moves up to nine or down to three based on aggravating and mitigating factors argued at sentencing: the severity of the conduct, the defendant’s record, and the circumstances of the incident.
Section 245(b) itself does not include a fine provision, which sets it apart from other subsections of PC 245 that explicitly authorize fines up to $10,000. Subsection (b) prescribes only imprisonment. A mandatory restitution fine still applies to every felony conviction, along with court assessments and any victim restitution the court orders, so the financial side of the sentence is real even without a statutory fine written into the offense.
There is no county jail option. The statute mandates state prison, which separates 245(b) from the wobbler subsections of PC 245 where a judge can choose jail instead.
Enhancements That Lengthen the Sentence
The base triad is often just a starting point. If the assault caused serious physical harm, the court can add a consecutive three-year enhancement for great bodily injury under Penal Code 12022.7. That jumps to five years if the victim was left comatose, paralyzed, or was 70 or older. A domestic violence circumstance carries its own enhancement of three, four, or five additional years.2California Legislative Information. California Penal Code PEN 12022.7
The separate firearm-use enhancement under Penal Code 12022.5 generally does not apply here because use of a firearm is already an element of the offense. That enhancement, which adds three, four, or ten years for personal firearm use during a felony, specifically excludes crimes where firearm use is baked into the charge itself. Prosecutors would need a separate felony count for it to attach.
Strike Status and the 85 Percent Rule
This is where the long-term damage shows up. PC 245(b) is listed as a serious felony under Penal Code 1192.7(c), which specifically includes assault with a semiautomatic firearm.3California Legislative Information. California Penal Code PEN 1192.7 – Plea Bargaining Prohibitions It also qualifies as a violent felony under Penal Code 667.5(c), which triggers the harshest custody credit restrictions in the system.
Ordinary inmates can earn day-for-day credits that cut their time roughly in half. A violent felony conviction changes the math. Under Penal Code 2933.1, a person convicted of a violent felony can earn no more than 15 percent credit against the sentence.4California Legislative Information. California Penal Code PEN 2933.1 That means serving at least 85 percent of the imposed term. On a nine-year sentence, the gap between standard credits and the 85 percent rule runs to roughly three additional years behind bars.
The strike follows you permanently. If you pick up any new felony afterward, one prior strike doubles the sentence for the new offense. A later serious or violent felony conviction with two prior strikes triggers an indeterminate life sentence with a 25-year minimum term.5California Legislative Information. California Penal Code PEN 667 After Proposition 36 passed in 2012, the 25-to-life provision generally requires the new offense to also be serious or violent, though certain gun-related felonies remain among the exceptions that trigger a life sentence regardless.6Legislative Analyst’s Office. Proposition 36 – Three Strikes Law Sentencing for Repeat Felony Offenders The strike cannot be expunged.
Lifetime Loss of Firearm Rights
A conviction under PC 245(b) triggers a lifetime ban on owning, purchasing, or possessing firearms under both state and federal law. California Penal Code 29800 prohibits any person convicted of a felony from possessing firearms, and for felonies involving dangerous weapons, state law offers essentially no path to restoration. Even a gubernatorial pardon cannot restore firearm rights when the underlying conviction involved a dangerous weapon.
Federal law under 18 U.S.C. 922(g)(1) imposes a separate lifetime ban on firearm possession for anyone convicted of a crime punishable by more than one year of imprisonment.7Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The three-year minimum under 245(b) clears that threshold easily. The federal prohibition applies independently of state law, and violating it is itself a separate felony.
Immigration Consequences for Non-Citizens
Non-citizens face severe immigration exposure. Federal immigration law makes any non-citizen deportable for a conviction involving the use, ownership, possession, or carrying of a firearm in violation of any law.8Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens An assault conviction involving a semiautomatic firearm falls squarely within that ground, and the trigger exists independently of the sentence imposed.
A 245(b) conviction may also qualify as an aggravated felony if a sentence of one year or more is imposed, since the offense involves a crime of violence. The three-year minimum virtually guarantees meeting that threshold. Aggravated felony status eliminates most forms of discretionary relief from removal, including cancellation of removal and, in many cases, asylum. A non-citizen facing this charge should consult an immigration attorney before entering any plea, because even a reduced charge can carry deportation consequences depending on how the plea is structured.
Other Collateral Consequences
The formal sentence is only part of what a conviction costs. A violent felony record affects professional licensing, employment, and housing. California licensing boards maintain strict policies on violent felony convictions: teaching credentials face potential permanent disqualification, healthcare licenses undergo case-by-case review with possible suspension or revocation, and contractors, engineers, and similar professionals face board investigations and practice restrictions.
Voting rights are suspended while serving the prison sentence but are restored on release under current California law. The strike itself remains on the record permanently.
Why Plea Deals Are Hard to Get
Because 245(b) is a serious felony, California sharply limits the prosecutor’s ability to offer a plea. Penal Code 1192.7 prohibits plea bargaining in serious felony cases unless the prosecution lacks sufficient evidence, a key witness is unavailable, or the reduced charge would not substantially change the sentence.3California Legislative Information. California Penal Code PEN 1192.7 – Plea Bargaining Prohibitions In practice, the most common path to a reduced charge requires the prosecution to acknowledge a real weakness in the case. The restriction covers bargaining over charges and sentencing, not just dismissals.
Where Defense Strategy Concentrates
The gap between PC 245(b) and PC 245(a)(2), the lower subsection for assault with a non-semiautomatic firearm, is where many cases are fought. Dropping to 245(a)(2) turns a straight felony into a wobbler, opens up county jail as an option, cuts the maximum prison term roughly in half, and removes the automatic strike classification.
Defenses that can produce that result or an acquittal usually target one of three elements. The first is the mechanical classification of the weapon: if the firearm was a revolver, bolt-action rifle, pump-action shotgun, or any firearm that does not self-load after each trigger pull, 245(b) does not apply. Defense experts routinely examine the weapon to confirm whether every part needed for semiautomatic function was present and operational.
The second is present ability. If the firearm was missing critical components that prevented it from firing, the defense can argue the “present ability” element of assault was not satisfied.9California Legislative Information. California Penal Code PEN 240 – Assault A stripped lower receiver or a gun missing its bolt carrier can support that argument. The showing is fact-intensive and usually turns on expert testimony about the weapon’s condition at the time of the incident.
The third is the willful-act element. If the firearm discharged during a struggle, a fall, or a mechanical malfunction, the defense can argue the act was not willful. The prosecution must prove the act was deliberate, so the line between an involuntary and a willful discharge can decide the case.
Self-defense is also available on its own terms. California permits deadly force when a person reasonably believes they face an imminent threat of death or serious bodily harm. The standard is both subjective and objective: an actual belief the threat was real, and a reasonable person in the same circumstances would have agreed. Inside the home, the law presumes the fear was reasonable when force is used against someone who unlawfully and forcibly entered.10California Legislative Information. California Penal Code PEN 198.5 Outside the home, the defense carries the burden of establishing reasonable fear from the circumstances of the encounter.
