This is a case about a gun that could not shoot. Defendant-appellant Pedro Rivera appeals from a judgment of the United States District Court for the Southern District of New York (Gerard E. Lynch, Judge) convicting him, following a jury trial, of unlawful possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1). On appeal, Rivera argues (1) that the jury’s verdict was not supported by sufficient evidence because the defective weapon in question did not meet the definition of a “firearm” set forth in 18 U.S.C. § 921(a)(3), and (2) that the district court constructively amended the indictment by charging the jury that the definition of a firearm included its “frame or receiver.” We affirm.
BACKGROUND
The evidence offered at trial established the following. On February 8, 2003, two New York City police officers saw Rivera and two others allegedly smoking marijuana in front of a Bronx social club. When the officers approached, Rivera tried to get away, but he ultimately was arrested along with the other men. A search incident to his arrest revealed a loaded .380 caliber semi-automatic pistol in Rivera’s pant leg. The weapon was subsequently determined to be inoperable because (1) the firing pin was broken, and (2) the firing-pin channel was peened over, or flattened.
Near-the close of the government’s case, Rivera moved, pursuant to Federal Rule of Criminal Procedure 29, for a directed verdict of acquittal. He contended that the evidence at trial was “legally insufficient because the weapon is simply inoperable” and “[i]t is not something that can be readily converted into a .[weapon] that is capable of firing a projectile.” The district court denied the motion, explaining that “[t]he case law outside the Second Circuit and in the district courts of this circuit is unanimous that inoperability is, not a defense.” .
Rivera presented no witnesses. He was convicted on the single count of possession of a firearm by a convicted felon and sentenced principally to 63 months’- imprisonment. This appeal followed.
DISCUSSION
I. An Inoperable Weapon is a “Firearm” Under 18 U.S.C. § 921(a)(3)
Rivera argues that the weapon he possessed did not meet the statutory defi *286 nition of a “firearm” contained in 18 U.S.C. § 921(a)(3), and thus no reasonable juror could have found him guilty of violating § 922(g)(1), the felon-in-possession statute. He advances two arguments as to why the weapon is not a firearm: (1) that it is inoperable, or, alternatively, (2) that it has been has been redesigned and cannot “readily be converted to expel a projectile.” His position is without merit.
Title 18 U.S.C. § 922(g) provides that “[i]t shall be unlawful for any person ... who has been convicted in any court of[ ] a crime punishable by imprisonment for a term exceeding one year” to “possess in or affecting commerce, any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.” The term “firearm” is defined, in relevant part, as “any weapon ... which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; [or] the frame or receiver of any such weapon .... ” 1 Id. § 921(a)(3).
Although we have yet to answer the question, every other circuit to consider it has concluded that an inoperable weapon falls within § 921(a)(3)’s definition of a “firearm.”
See, e.g., United States v. Adams,
Where a weapon designed to fire a projectile is rendered inoperable, whether on purpose or by accident, it is not removed from the statute’s purview; although it is temporarily incapable of effecting its purpose, it continues to be “designed” to fire a projectile.
See, e.g., United States v. Ruiz,
In this case, the testimony of Special Agent Robert Berger established at trial, and Rivera conceded at oral argument, that the gun was originally designed to fire a bullet. That the firing pin and firing-pin channel were damaged did not fundamentally alter the gun’s design.’ Accordingly, we agree with the district court that an inoperable pistol is a firearm within the meaning of § 921(a)(3).
We recognize, however, that a weapon originally designed to fire a pro
*287
jectile could perhaps be so redesigned or modified to remove it from § 921(a)(3)’s coverage — the second argument that Rivera presses. For - example, a gun with a barrel filled with lead, maybe for use as a theatrical prop, might perhaps no longer be deemed “designed to” or “readily be converted” to fire a bullet.
See, e.g., United States v. Wada,
As the evidence showed that the weapon was “designed to ... expel a projectile by the action of an explosive,” we need not consider, whether it also showed that the weapon “may readily be converted to expel a projectile by the action of an explosive.” The statute was clearly written in the disjunctive. The government need only show that the weapons was either “designed to” or “may readily be converted.” 18 U.S.C. § 921(a)(3). It need not demonstrate both.
II. Constructive Amendment
Rivera argues that the district judge erred in constructively amending the indictment by charging the jury that the offense of firearm possession could be satisfied by the possession of a “frame or receiver.” “An indictment is constructively amended when the proof at trial broadens the basis of conviction beyond that charged in the indictment.”
United States v. Patino,
[constructive amendment occurs when the terms of the indictment are in effect altered by the presentation of evidence and jury instructions which so modify essential elements of the offense charged that there is a substantial likelihood that the defendant may have been convicted of an offense other than that charged in the indictment.
United States v. Wallace,
In his jury instructions, Judge Lynch defined a firearm to include both (1) a weapon designed to or readily convertible to expel a projectile, and (2) a frame or receiver of any such weapon. Because the indictment charged Rivera with the unlawful possession of “a firearm, to wit, a loaded .380 Davis Industries semiautomatic pistol,” Rivera contends that the only offense of which he had notice was possession of a loaded gun and that, by instructing the jury that a firearm also encompasses a frame or receiver, Judge Lynch constructively amended the indictment. Rivera’s argument is unpersuasive.
The statutory definition of a firearm includes a frame or receiver, and the indictment did not limit the definition of firearm to a loaded weapon. Rivera, therefore, plainly had “notice of the ‘core of criminality’ ” for which he was tried and of which he was convicted.
Danielson,
Similarly, to the extent he advances it, Rivera’s prejudicial-variance argument is
*288
without merit. There was no variance. And in any event, Rivera was not prejudiced because the government provided him with notice that it also intended to rely upon the frame-or-receiver definition at trial.
See United States v. Helmsley,
We have considered Rivera’s other contentions and find that they are without merit.
CONCLUSION
For the foregoing reasons, the judgment of the district court is hereby Affirmed. 2
