18 U.S.C. § 922(g) & § 924(c): Federal Firearm Offenses, Prohibited Persons & Mandatory Minimums

1. Statutory Overview: Two Pillars of Federal Gun Prosecution

While state courts handle most everyday weapons charges, federal prosecutors aggressively enforce 18 U.S.C. § 922 and 18 U.S.C. § 924 through joint ATF and local task-force initiatives. Two provisions dominate federal dockets: § 922(g), which bars nine specific categories of people from possessing firearms or ammunition, and § 924(c), which imposes mandatory consecutive prison time whenever a gun is used or possessed in connection with a federal drug trafficking crime or crime of violence.

2. Prohibited Persons Under 18 U.S.C. § 922(g)

Section 922(g) makes it a federal felony for any person in the following categories to ship, transport, possess, or receive any firearm or ammunition that has traveled in interstate or foreign commerce (which covers virtually every commercially manufactured firearm and round of ammunition):

• § 922(g)(1): Persons convicted in any court of a crime punishable by imprisonment for a term exceeding 1 year (felons, even if probation was originally imposed);
• § 922(g)(2): Fugitives from justice;
• § 922(g)(3): Unlawful users of or addicts to any controlled substance;
• § 922(g)(4): Persons adjudicated as a mental defective or involuntarily committed to a mental institution;
• § 922(g)(5): Aliens unlawfully in the United States or admitted under most nonimmigrant visas;
• § 922(g)(6)–(7): Dishonorably discharged veterans and persons who have renounced U.S. citizenship;
• § 922(g)(8): Persons subject to qualifying domestic violence restraining orders; and
• § 922(g)(9): Persons convicted of a misdemeanor crime of domestic violence.

4. ACCA (§ 924(e)) & First Step Act Reforms

Two crucial Supreme Court and legislative limits govern the harshest firearm enhancements:

• No More First-Time “Stacking” Under § 924(c): Before December 2018, prosecutors could charge two § 924(c) counts in the same indictment and force a 25-year add-on for the second count. The First Step Act amended § 924(c)(1)(C) so the 25-year minimum only triggers if a defendant already had a final prior § 924(c) conviction before committing the second offense.
• Jury Findings for ACCA “Different Occasions”: Under Erlinger v. United States (2024), whether three prior convictions occurred on “occasions different from one another” to trigger the 15-year Armed Career Criminal Act mandatory minimum must be proven unanimously to a jury beyond a reasonable doubt (or admitted by the defendant), not decided solely by a judge at sentencing.

5. Legal Defenses in Federal Gun Prosecutions

• Constructive Possession Challenges: When a firearm is found inside a shared home or multi-passenger vehicle, prosecutors must prove the defendant both knew the gun was there and had the power and intent to control it.
• “In Furtherance Of” Nexus (§ 924(c)): Merely having an unloaded gun in a closet while selling small quantities elsewhere does not automatically prove possession “in furtherance of” drug trafficking (Ceballos-Torres factors).
• Predicate Offense Challenges: Challenging whether a prior state offense categorically qualifies as a “crime of violence” under the elements clause (United States v. Davis, Taylor).

Practical Sentencing Example & Collateral Consequences

Illustrative Scenario: During an arrest for distributing 60 grams of fentanyl (§ 841(b)(1)(B), 5-year minimum), officers recover a loaded handgun tucked inside the driver’s center console to protect the drug proceeds. If prosecutors convict on both § 841 and 18 U.S.C. § 924(c)(1)(A)(i), the judge must impose at least 5 years on the drug count plus a mandatory consecutive 5 years on the gun count — totaling at least 10 years (120 months) in federal prison.

Collateral Consequences: Any felony firearm conviction causes permanent nationwide forfeiture of Second Amendment firearm rights under § 922(g)(1) and disqualifies inmates from First Step Act earned-time credits on § 924(c) portions of their sentence.
