Prohibited Person Firearms – What You Need to Know
Federal firearms charges carry some of the harshest penalties in the entire federal system. Calculate sentencing for various categories of prohibited persons possessing firearms.
If you’re facing firearms charges, here’s what you need to understand: 18 USC §924(c) imposes mandatory consecutive sentences – 5 years for possession, 7 for brandishing, 10 for discharge – and these sentences run on top of any other sentence. A second §924(c) conviction carries 25 years to life. This is serious. But there are defenses, there are arguments, and there are strategies that an experienced federal defense attorney can use to fight for a better outcome.
How Federal Firearms Sentencing Works
The first question in any §924(c) case is whether the predicate offense qualifies as a “crime of violence.” After the Supreme Court’s decision in Davis v. United States (2019), many offenses that previously served as §924(c) predicates no longer qualify. This is a major development – and it means that §924(c) charges can sometimes be challenged and defeated entirely. Many attorneys don’t even raise this argument. We always do.
For felon-in-possession cases under §922(g), the guideline calculation under §2K2.1 depends heavily on your prior convictions. If you have a prior “crime of violence” or “controlled substance offense,” the base offense level jumps significantly. But the definition of these terms has been subject to extensive litigation, and what counts as a qualifying prior varies by circuit. You need an attorney who stays current on this case law – because it changes frequently.
The Armed Career Criminal Act (ACCA) adds another layer. If you have three qualifying predicate offenses, you face a 15-year mandatory minimum. But qualifying priors are determined using the categorical approach, which requires examining the elements of the prior offense – not the underlying facts. Many convictions that look like they qualify on the surface actually don’t when you apply the correct legal analysis.
What Most People Don’t Realize About Prohibited Person Firearms
The biggest thing people miss in firearms cases is that §924(c) charges are negotiable. The difference between pleading to a §924(c) count and having the firearm reflected only in a guideline enhancement can be the difference between 5+ years of mandatory consecutive time and a 2-level increase. This is where experienced plea negotiation makes all the difference.
For felon-in-possession cases, constructive possession is often more defensible than people realize. The government has to prove you had knowledge, access, and dominion over the firearm. If the gun was found in a shared residence or vehicle, that’s not automatic possession – and a suppression motion challenging the search can sometimes eliminate the evidence entirely.
Why You Need the Right Federal Defense Attorney
Federal firearms cases have mandatory minimums, consecutive sentencing requirements, and guideline calculations that can produce devastating results for defendants who don’t have experienced representation. You need an attorney who understands the post-Davis landscape, knows how to challenge predicate offenses, and can negotiate effectively with federal prosecutors to eliminate or reduce the most damaging charges.

Frequently Asked Questions
What categories of "prohibited persons" are covered by 18 U.S.C. § 922(g), and how did Rehaif change the knowledge requirement?
Section 922(g) prohibits possession by nine categories: felons (g)(1), fugitives (g)(2), unlawful drug users (g)(3), persons adjudicated mentally defective (g)(4), unlawful aliens (g)(5), persons dishonorably discharged (g)(6), persons who renounced citizenship (g)(7), persons subject to domestic violence restraining orders (g)(8), and persons convicted of domestic violence misdemeanors (g)(9). Rehaif v. United States (2019) held that the government must prove the defendant knew they belonged to the relevant prohibited category — not just that they knowingly possessed a firearm. This knowledge-of-status requirement has become a powerful defense tool, particularly for defendants who did not know their immigration status was unlawful or did not realize a prior conviction was classified as a felony.
How does the "unlawful user of a controlled substance" prohibition under § 922(g)(3) interact with state marijuana legalization?
Section 922(g)(3) prohibits firearm possession by anyone who is an "unlawful user of or addicted to any controlled substance." Because marijuana remains a Schedule I substance under federal law, lawful state marijuana users are federally prohibited persons — even in states where recreational use is legal. The Ninth Circuit upheld this prohibition in Wilson v. Lynch (2016), but post-Bruen, as-applied challenges are proliferating. Defense counsel should argue that disarming non-violent marijuana users is inconsistent with the historical tradition of firearms regulation, particularly given that no Founding-era analogue prohibited firearms possession by users of intoxicating substances. The temporal element is also critical — the defendant must be a "current" user, and past use alone is insufficient under most circuit precedent.
