Appellant was found guilty after trial by jury of robbery while armed. 1 He asserts on this appeal that the instruction given the jury by the trial court broadened the rangе of offenses which it could consider beyond that stated in the indictment, thereby effectively amending the indictment in violation of appellant’s cоnstitutional right *319 to indictment by grand jury. We affirm the conviction.
The indictment returned against appellant charged, in relevant part, that he robbed the complainant “while armed with a dangerous wеapon, that is, a pistol.” The evidence adduced at trial showed that the robbery was committed with a .22 caliber starter pistol. A government witness testified that the gun could “probably” be modified into an operable firearm, but there was no evidence that it had been so modified. The trial court instructed the jury, over defense counsel’s objection, 2 that it could convict appellant if it found he was armed with “any pistol or firearm or imitation thеreof.”
Appellant concedes that the instruction accurately reflected the statutory definition of armed robbery. 3 He argues, howevеr, that, under the indictment as it was phrased in this case, the jury could convict only if it found that he was armed with a genuine pistol, or at the very least, with an inherently dangerous weapon. He distinguishes imitation firearms from pistols and other dangerous weapons, and asserts that a conviction for use of an imitation weapon may not be had under an indictment charging an offense while armed with a pistol or dangerous weapon. Correlatively, apрellant asserts that use of an imitation pistol must be specifically alleged in the indictment, since it is not generically a dangerous or deadly weаpon as are the others enumerated in § 22-3202. Further, it is argued that an indictment charging any armed offense must specify the weapon used in order sufficiently to inform the defendant of the nature of the charges against him. Applying these principles to the instant case, appellant urges that the gоvernment was bound by the grand jury’s choice of “a dangerous weapon, that is, a pistol”, and that the instruction allowing the jury to convict if it found any of a brоader range of weapons was used in the crime impermissibly amended the indictment to include offenses not passed upon by the grand jury.
An accused in a serious criminal case is constitutionally entitled to be tried on an indictment which has in each material particular been approved by a grand jury.
Gaither v. United States,
134 U.S. App.D.C. 154, 164,
In our view, the instant case involves neither amendment of the indictment nor prejudicial variance requiring reversal of the conviction. The issue raised here is similar to the issue considered in
Jackson v. United States,
This court ruled in
Harris v. United States,
D.C.App.,
The remaining quеstion, then, is whether an indictment need allege the specific type of weapon used in perpetrating the offense of armed robbery. Wе think not. The critical added element of § 22-3202 is that the crime is committed by one armed with a dangerous or deadly weapon. This list of weapons in that section merely catalogues the ways in which the offense may be committed. Such specific facts need not be included in the indictment and when they are included are surplusage.
Jackson v. United States, supra,
at 278-79,
The indictment in this case charged appellant with robbery while armed with a dangerous weapon, and the prоof adduced at trial showed that he was so armed. The court’s instruction, rather than amending the indictment, did no more than explain the charges cоntained therein more fully than did the indictment itself. Appellant has not pressed a contention that he was prejudiced by a variance betweеn the allegation that a pistol was used in the robbery and the proof presented at trial, and we agree that such variance, if any, was harmless. 6
Accordingly, the judgment is
Affirmed.
Notes
. D.C.Code 1973, §§ 22-2901, 22-3202. The jury made no finding on related charges of robbery and assault with a dangerous weapon.
. Appellant requested an instruction that he сould be convicted under the indictment only if the jury found he was armed with “a pistol as such, that is, a pistol in the sense of arm or firearm.”
. D.C.Code 1973, § 22-3202 provides fоr punishment of one who commits a crime of violence while “armed with or having readily available any pistol or firearm (or imitation thereof) оr other dangerous or deadly weapon . . . .”
. D.C.Code 1973, § 22-2901.
. It is not required in this jurisdiction that the government prove that the gun used in an armed offense was loaded or оperable.
United States v. Prater,
. This case is analogous to
United States v. Marshall,
This is not a case, as was
Stirone v. United States, supra,
where a set of facts wholly different from that prеsented to the grand jury was relied on by the prosecution at trial.
