In brief: 442 people were sentenced for firearms offenses in the Southern District of California in fiscal years 2016 to 2025, and 419 (95%) received a prison term. The median prison term was 24 months (2 years), lower than the 42 months for firearms cases in all 94 districts. 17% of sentences were within the guideline range, compared with 52% in all districts.
This post uses the U.S. Sentencing Commission's records of 442 people sentenced in federal court in fiscal years 2016 to 2025. Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
Criminal History Differs From Other Categories
In this group, 25% were in the lowest criminal history category, category I, and 28% were in the highest, category VI. Criminal history is a score the Commission's rules use to place a person on the guideline table.
Court-martial records have no criminal history field, so no comparison with courts-martial can be made on this point.
Prison Terms for Firearms Offenses
419 of the 442 people (95%) received a prison term, and 18 (4%) received probation only, with no prison or other confinement. In all districts, 94% were sent to prison.
Among those sent to prison, the median prison term was 24 months. A quarter received 46 months or more, and a quarter received 13 months or less. The median for all offenses in this district was 15 months.
These are terms imposed, not time served.
Few Sentences Within the Range
The guideline range is the range produced by the Commission's rules for each case. 75 sentences (17%) were within it. For all offenses in this district, 15% were within the range.
280 sentences (63%) were below the range at the government's request, and 82 (19%) were below it without a government request. 5 (1%) were above the range.
Trials Were Less Common Than Pleas
422 people (95%) pleaded guilty, and 20 were convicted after a trial. In all districts, 97% pleaded guilty.
The median prison term after a guilty plea was 24 months. After a trial it was 33 months, based on 20 people sent to prison. 97% of the guilty pleas had a written plea agreement, and 2% were straight pleas.
The Guideline in Nearly Every Case
"Firearms" is the U.S. Sentencing Commission's offense category. 418 cases used §2K2.1 (Unlawful Receipt, Possession, or Transportation of Firearms or Ammunition), and 1 used §2K1.5 (Possessing Dangerous Weapons or Materials While Boarding or Aboard an Aircraft).
A mandatory minimum prison term applied to 12 of the 441 people with that information (3%). Firearms cases were 1% of the 32,099 people sentenced in the district.
Supervised Release and Fines
414 people (94%) were ordered to serve supervised release after prison, with a median term of 36 months. A fine was ordered for 12 people (3%), and restitution for 2.
Yearly Counts
147 people were sentenced in fiscal years 2016 to 2019, and 295 in fiscal years 2020 to 2025. The yearly counts range from 29 to 60.
The yearly medians in the table range from 21.5 months in 2018 to 35 months in 2023. The records cannot show what caused any change, and they count only people who were convicted and sentenced.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 41 | 24 months | 98% |
| 2017 | 29 | 31.5 months | 93% |
| 2018 | 47 | 21.5 months | 91% |
| 2019 | 30 | 24 months | 93% |
| 2020 | 34 | 25.8 months | 100% |
| 2021 | 48 | 27 months | 98% |
| 2022 | 59 | 24 months | 100% |
| 2023 | 60 | 35 months | 95% |
| 2024 | 44 | 28 months | 93% |
| 2025 | 50 | 24 months | 92% |
What the Records Do Not Show
The records do not describe the facts of any case. They do not show people who were charged and not convicted. The district contains Camp Pendleton, Marine Corps Air Station Miramar, and San Diego, which appear in the court-martial data, but courts-martial are tried in military courts and are not part of this federal data.
How We Counted
Everyone sentenced in federal court in the Southern District of California (U.S. Sentencing Commission district label "California South") in fiscal years 2016 to 2025 whose offense type was "Firearms" (442). Offense types are the Commission's OFFGUIDE categories.
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
Mandatory minimum sentences. Many federal statutes on drugs, images of child exploitation, child sex abuse, and firearms carry mandatory minimum prison terms. The UCMJ has mandatory minimums only for a few offenses (a dishonorable discharge or dismissal for rape and sexual assault, and life for premeditated murder). Federal sentences for these offenses are partly set by Congress, not by the judge.
