OPINION OF THE COURT

The issue presented for our consideration is whether a single, unanswered question alluding to alleged unrelated criminal activity1 warrants the granting of a new trial despite the fact that an immediate cautionary instruction and a proper direction in the charge was given to the jury.

On May 6, 1983, at approximately 1:30 a.m. Allan Joseph Nowicki was shot, in the back, with a .38 caliber handgun at his residence in Tinicum Township, Pennsylvania. Stephen Quintín Morris (appellee) was arrested on May 13, 1983 and charged with attempted homicide, aggravated assault, simple assault, recklessly endangering another person and possession of an instrument of crime.

*172Appellee was found guilty on all charges and filed a Motion In Arrest of Judgment and For A New Trial, alleging, inter alia, that the trial court erred in allowing the Commonwealth to cross-examine him concerning an alleged unrelated crime. Appellee’s motion was denied. The basis for the denial of the motion was that the curative instruction given to the jury eradicated any taint of prejudice and thus assured appellee of a fair trial. The trial court also found that “the offense alluded to in questioning, carrying a weapon without a permit, is not, as a general matter, of such a heinous nature as to highly inflame the passion or prejudice of the jury.” Slip opinion at 4. Appellee was sentenced to 5 to 10 years imprisonment on the attempted homicide and aggravated assault charges; 1 to 2 years imprisonment, to be served concurrently, on the recklessly endangering charge and 1 to 5 years imprisonment, to be served consecutively, on the possession of an instrument of crime charge.

Appellee then appealed to Superior Court.2 By memorandum opinion filed May 3, 1985, appellee’s judgment of sentence was vacated and the case remanded for a new trial. Commonwealth v. Morris, 345 Pa.Super. 619, 496 A.2d 853 (1985) [table].3 The Superior Court found the *173reference to alleged unrelated criminal activity engaged in by appellee to be prejudicial and that, “there is no doubt that the offensive testimony was elicited deliberately. The curative instructions, although prompt, could not overcome the prejudice.” Mem. op. at 5. This Court granted the Commonwealth's petition for allowance of appeal and we now reverse.

During cross-examination of appellee, appellee testified that he had “all types of guns,”4 that he was a gun collector and that all of his guns were in the Bahamas. Upon further questioning, appellee admitted that he owned approximately six .38 caliber guns (the caliber used to shoot the victim), that he did, in fact, have approximately three different guns in the United States — a .38, a .44, and a .41 Magnum and, that he had a gun “for protection” at the liquor store, where he worked, in New Jersey. During the course of cross-examination of appellee, the following exchange, which is the focus of this case, took place:

BY MR. GOLDMAN [for the Commonwealth]:

*174Q Are you licensed in the United States to carry a firearm?

A Yes.

Q You are?

A Yes, permit.

Q Where did you obtain that permit?

A Miami, Florida.

Q For just Florida?

A Yes.

Q Do you have that permit in your possession now? A No.

Q Did you have it in your possession when you were arrested?

A No.

Q Did you have a permit to carry a possessive firearm in New Jersey?

A No.

Q But yet, in violation of the law, you possess this firearm in New Jersey ?

BY MR. NASSHORN [counsel for appellee]: Objection. THE COURT: Sustained.

Members of the jury, that is not an issue in this case and it’s not to be considered.

This case to be decided based on the evidence presented as to whether or not you believe beyond a reasonable doubt that the Commonwealth has sufficient evidence to convict the defendant of some or all of the charges involved. You are not to consider anything like that.

Transcript at p. 198-99. (emphasis supplied) In the charge to the jury, the trial court provided further curative instructions.

There has been some reference in this case, although a passing reference, to whether or not the defendant had a gun permit____ You’re not to try, to speculate as to whether the defendant in fact committed other crimes. You are to zero in on what occurred in the early morning *175hours of May 6, 1983, and of course the other facts in the case.

Transcript at 251-52.

Appellee argues that reference to his alleged prior criminal activity was prejudicial and stripped him of the presumption of innocence. The Commonwealth argues that the line of questioning was to impeach appellee and to show that appellee had access to firearms previously purchased by him and that any prejudice that may have resulted from the one question was cured by the immediate cautionary instruction given to the jury. We agree.

Our review of the grant or denial of a new trial is limited to determining whether the trial court abused its discretion or committed an error of law. Commonwealth v. White, 482 Pa. 197, 393 A.2d 447 (1978). The trial court, in the instant case, was correct in denying appellee’s motion for a new trial.

As a general rule, evidence of crimes unrelated to the charge for which the defendant is being tried, is inadmissible. Commonwealth v. Martin, 479 Pa. 63, 387 A.2d 835 (1978); Commonwealth v. Turner, 454 Pa. 439, 311 A.2d 899 (1973).5 There is no per se rule that requires a new *176trial for a defendant every time there is a reference to prior criminal activity. Commonwealth v. Heaton, 504 Pa. 297, 472 A.2d 1068 (1984). “[W]e have never ascribed to the view that all improper references to prior criminal activities necessarily require the award of a new trial as the only effective remedy.” Commonwealth v. Williams, 470 Pa. 172, 178, 368 A.2d 249, 252 (1977). Further, the reference to prior criminal activity must be prejudicial to the defendant, with prejudice resulting “where the testimony conveys to the jury, either expressly or by reasonable implication, the fact of a prior criminal offense.” Commonwealth v. Nichols, 485 Pa. 1, 4, 400 A.2d 1281, 1282 (1979) (emphasis in original omitted).

However, it is possible to eradicate any prejudice resulting from reference to prior criminal activity by the defendant.

Our decisions have indicated that there are situations where the taint, resulting from an improper reference to an unrelated criminal act, may be expunged without resort to the extreme remedy of aborting an otherwise fair trial. It is suggested that our decisions in Commonwealth v. Groce, 452 Pa. 15, 303 A.2d 917 (1973) and Commonwealth v. Allen, supra [448 Pa. 177, 292 A.2d 373 (1972) ] would indicate otherwise. We do not agree. In Groce, supra and Allen, supra, the challenged references to prior and unrelated criminal activities were permitted by the trial court for the jury’s consideration. In the instant action, the testimony was stricken and the jury immediately cautioned.

Commonwealth v. Williams, 470 Pa. at 178, 368 A.2d at 252. An immediate curative instruction to the jury may alleviate any harm to the defendant that results from reference to prior criminal conduct. See, Commonwealth v. Whitfield, 474 Pa. 27, 376 A.2d 617 (1977) (jury was instructed to disregard a witness’s testimony that he had previously seen defendant “work people over”); Common*177wealth v. Williams, supra, (jury was instructed to disregard a witness’s testimony concerning defendant’s unrelated use of drugs); Commonwealth v. Povish, 479 Pa. 179, 387 A.2d 1282 (1978) (jury instructed to disregard testimony concerning a robbery for which defendant was charged but not then being tried); and Commonwealth v. Richardson, 496 Pa. 521, 437 A.2d 1162 (1981), (jury instructed to disregard a witness’s testimony concerning a prior burglary of the same residence for which defendant was then on trial).

“[Wjhether the exposure of the jury to improper evidence can be cured by an instruction depends upon a consideration of all the circumstances.” Commonwealth v. Richardson, supra, 496 Pa. at 526, 437 A.2d at 1165. One of the circumstances to be considered is the nature of the crime. The instant case presents us with a single, unanswered question asked of appellee alluding to his alleged violation of the law of New Jersey by possessing a firearm without a permit. There is no doubt that the Commonwealth’s question was improper. This could have conveyed to the jury, with possible resultant prejudice to appellee, the existence of prior criminal activity. However, we agree with the trial court that the alleged offense alluded to, carrying a firearm in New Jersey without a permit, is not of such a heinous nature as to highly inflame a jury. Possession of a firearm without a permit is not the type of crime, the nature of which is likely to cause a jury to be so incensed as to lose sight of the ultimate question before them — whether appellee shot the victim.

An additional circumstance to be considered is whether or not the trial court gave cautionary instructions to the jury. After an inference of unrelated criminal activity has been conveyed to a jury, minimally, cautionary instructions must be given. In the instant case, immediately after the question was asked, and prior to any answer being elicited from appellee, the trial court sustained the objection of *178appellee’s counsel and immediately cautioned the jury to disregard any reference to alleged prior criminal activity on the part of appellee. No motion for mistrial was made by appellee’s counsel at this time, indicating his satisfaction with the instruction to the jury. The trial court, in the charge to the jury, again admonished the jury to disregard any reference to alleged prior criminal activity on the part of appellee. No objection to this charge was made by appellee, indicating his satisfaction with the charge. We find, in the instant case, that any prejudice to appellee from the limited reference to alleged prior criminal activity was effectively neutralized by the trial court’s immediate cautionary instruction to the jury and admonition in the jury charge. See, Commonwealth v. Martinolich, 456 Pa. 136, 318 A.2d 680, cert. denied, 419 U.S. 1065, 95 S.Ct. 651, 42 L.Ed.2d 661 (1974) (improper comment by the Commonwealth cured by immediate cautionary instruction and jury charge).

A defendant is entitled to receive a fair trial but not a perfect trial. Bruton v. United States, 391 U.S. 123, 88 S.Ct. 1620, 20 L.Ed.2d 476 (1968). A review of the record as a whole reveals that appellee did receive a fair trial. The Commonwealth’s error was cured by the cautionary instruction and the trial court was correct in its denial of the motion for new trial.

The order of Superior Court vacating appellee’s judgment of sentence and remanding the case for new trial is reversed and appellee’s judgment of sentence is reinstated.

concurring.

I concur in the result. As the majority implies in footnote 3, at 172-173 n. 3, appellant waived the only issue in this case by failing to move for a mistrial at trial. Thus, I would simply hold that since the issue was not raised below it is waived.
