18 U.S.C. § 924(c) Defense — Firearm During a Drug or Violent Crime

A § 924(c) count changes the arithmetic of a federal case completely. It is not folded into the Guidelines range — it sits on top of it, and it must run consecutively.

It is also the count most often successfully attacked, because its predicate definitions have been repeatedly cut back by the Supreme Court.

What the statute does

18 U.S.C. § 924(c) applies to any person who, during and in relation to a drug trafficking crime or a crime of violence, uses or carries a firearm, or who, in furtherance of such a crime, possesses a firearm.

The sentence is mandatory, consecutive to every other sentence, and cannot be reduced by the court or served concurrently with the predicate offense.

The tiered minimums

• 5 years — possession, use, or carrying
• 7 years — if the firearm was brandished
• 10 years — if the firearm was discharged
• 30 years — if the firearm was a machine gun, a destructive device, or was equipped with a silencer or suppressor
• Life — in defined circumstances on a second or subsequent conviction

The 30-year tier is why drug cases involving an auto sear or "Glock switch" carry exposure so far beyond what defendants expect.

Use or carry, versus possession in furtherance

These are different offenses with different proof requirements, and the distinction has real history.

In Bailey v. United States, 516 U.S. 137 (1995), the Supreme Court held that "use" requires active employment of the firearm — a gun locked in a trunk was not "used." Congress responded by adding the "possession in furtherance" prong, which is now the more commonly charged theory.

"In furtherance" still requires a nexus between the weapon and the drug offense. Mere presence in the same place is not enough. Courts look at whether the gun was loaded, accessible, proximate to drugs or proceeds, whether it was legally possessed, and whether the circumstances suggest it was there to protect the operation.

That nexus is the primary battleground in possession cases. A lawfully owned, unloaded hunting rifle in a bedroom closet, in a house where drugs were found in the kitchen, is a genuinely contestable § 924(c).

Note also Watson v. United States, 552 U.S. 74 (2007): a person who receives a firearm in trade for drugs does not "use" it within the meaning of the statute.

Davis: the crime-of-violence definition was struck down

Section 924(c)(3) defines "crime of violence" two ways — subsection (A), the elements clause, and subsection (B), a residual clause covering offenses involving a substantial risk of physical force.

In United States v. Davis, 588 U.S. 445 (2019), the Supreme Court held the residual clause in § 924(c)(3)(B) unconstitutionally vague. Only the elements clause survives.

The consequence is significant and ongoing. A § 924(c) count predicated on a crime of violence is valid only if the predicate categorically requires the use, attempted use, or threatened use of physical force as an element. Many offenses that were treated as predicates before 2019 no longer qualify.

United States v. Taylor, 596 U.S. 845 (2022), extended this: attempted Hobbs Act robbery is not a crime of violence under the elements clause, because attempt requires only a substantial step, not the use or threat of force. Defendants sentenced on invalid predicates may have relief available through a § 2255 motion.

The First Step Act ended stacking

Before December 2018, the enhanced 25-year minimum for a "second or subsequent" § 924(c) conviction applied even where all the counts were charged in the same indictment. A first-time defendant with three § 924(c) counts faced 5 + 25 + 25 years, consecutive — routinely producing sentences of half a century for conduct that carried nothing like that on its face.

Section 403 of the First Step Act fixed it prospectively: the enhanced minimum now applies only where the prior § 924(c) conviction was final at the time of the current offense.

The change is not retroactive on its own terms. But for people serving stacked sentences, the unusually-long-sentence provision in the amended U.S.S.G. § 1B1.13 now expressly addresses gross disparities created by intervening changes in law — and stacked § 924(c) sentences are the paradigm case for it.

Aiding and abetting requires advance knowledge

In Rosemond v. United States, 572 U.S. 65 (2014), the Supreme Court held that to convict a defendant of aiding and abetting a § 924(c) offense, the government must prove the defendant had advance knowledge that a confederate would be armed — knowledge at a point when he still had a realistic opportunity to withdraw.

This matters enormously in multi-defendant drug cases. A participant who learned a co-defendant was carrying only once the transaction was underway has a defense, and it is a jury-instruction issue as well as a factual one.

Why dismissal of this count is the priority

Because the sentence is mandatory and consecutive, no Guidelines argument, variance argument, or mitigation reaches it. The safety valve does not apply to § 924(c), and a defendant who possessed a firearm in connection with the offense is generally disqualified from the safety valve on the drug counts too.

In practice this makes dismissal of the § 924(c) count — in exchange for a plea to the predicate, or on a legal challenge to the predicate's validity — the single most valuable objective available. Five years removed from the top of a sentence is worth more than any amount of argument about offense level.
