PRACTICE NOTE:  Under 18 USC 924(c) use of a firearm involving a crime of violence or drug trafficking is subject to various prison terms depending on the type of weapon used.  Hence, failure to include the type of firearm in an indictment under the statute is a jurisdictional defect that precludes harmless error analysis. (See  U.S. v. Tran (2nd Cir. 2000) 234 F3d 798, 809; see also United States v.Castillo (2000) 530 US 120 [120 SCt 2090; 147 LEd2d 94] [type of firearm used or carried in a 18 USC 924(c) violation is an element of the offense]; United States v. Spruill (4th Cir. 1997) 118 F3d 221, 227 ["It is well established . . . that failure to recite an essential element of the offense in the indictment is not amenable to harmless error review"]; United States v. Santeramo (2d Cir. 1995) 45 F3d 622, 624 [criminal indictment must (1) contain all of the elements of the offense so as to fairly inform the defendant of the charges against him, and (2) enable the defendant to plead double jeopardy in defense of future prosecutions for the same offense]
