Petitioners Abbott and Gould, defendants in unrelated prosecutions, were charged with drug and firearm offenses, including violation of 18 U. S. C. §924(c), which prohibits using, carrying, or possessing a deadly weapon in connection with “any crime of violence or drug trafficking crime,” §924(c)(1). The minimum prison term for a §924(c) offense is five years, §924(c)(1)(A)(i), in addition to “any other term of imprisonment imposed on the [offender],” §924(c)(1)(D)(ii). Abbott was convicted on the §924(c) count, on two predicate drug-trafficking counts, and of being a felon in possession of a firearm. He received a 15-year mandatory minimum sentence for his felon-in-possession conviction and an additional five years for his §924(c) violation. Gould’s predicate drug-trafficking crime carried a ten-year mandatory minimum sentence; he received an additional five years for his §924(c) violation. On appeal, Abbott and Gould challenged their §924(c) sentences, resting their objections on the “except” clause prefacing §924(c)(1)(A). That clause provides for imposition of a minimum five-year term as a consecutive sentence “[e]xcept to the extent that a greater minimum sentence is otherwise provided by [§924(c) itself] or by any other provision of law.” Abbott urged that the “except” clause was triggered by his 15-year felon-in-possession sentence; Gould said the same of the ten years commanded by his predicate trafficking crime. The Third Circuit affirmed Abbott’s sentence, concluding that the “except” clause “refers only to other minimum sentences that may be imposed” for §924(c) violations. Gould fared no better before the Fifth Circuit.

Held: A defendant is subject to the highest mandatory minimum specified for his conduct in §924(c), unless another provision of law directed to conduct proscribed by §924(c) imposes an even greater mandatory minimum. Pp. 5–18.
