Using or Carrying a Firearm During Any Crime of Violence or Drug Trafficking Crime (18 U.S.C. Sec. 924(c)(1)) (revised 2017) is a federal law that imposes a mandatory minimum sentence on individuals who use or carry a firearm in the commission of certain violent or drug trafficking crimes. The law applies to any person who “uses or carries” a firearm during and in relation to any crime of violence or drug trafficking crime. The revised 2017 version of the law increases the minimum sentences and makes them harsher, including mandatory minimum sentences for certain types of firearms. The types of firearms mentioned in the law include semiautomatic assault weapons, machine guns, short-barreled rifles and shotguns, silencers, and destructive devices. The law also applies to individuals who possess a firearm in furtherance of a crime of violence or drug trafficking crime, even if the firearm is not used or carried during the commission of the crime. The law imposes different sentences for different types of firearms and offenses. For example, an individual who is convicted of using or carrying a firearm during and in relation to a crime of violence or drug trafficking crime can face up to 10 years in prison if the firearm is a semiautomatic assault weapon or a machine gun, up to 5 years in prison for any other firearm, and up to 30 years in prison if the firearm is a destructive device or silencer.
