The two issues in this case are: (1) the extent to which a trial judge is required to conduct an inquiry as to reasons a defendant requests a change of trial counsel when such a request is voiced on the eve of trial, and (2) whether the defendant’s trial counsel was ineffective. We conclude *656 that a judge should permit a defendant to give his reasons for a change in counsel and that trial counsel’s assistance was not ineffective. We affirm the defendant’s convictions of murder in the first dеgree and assault and battery by means of a dangerous weapon. 1
Briefly, the facts are as follows. The victim, Salvatore Sperlinga, was seated at a table in a social club in Somerville on the morning of January 4, 1980. The defendant came in the front door, asked for the victim, espied him, and pulled the trigger of a .32 caliber automatic pistol. The gun, however, misfired, and the victim ran toward a back room. Before he reached that destination he was struck by one bullet in the buttocks. Entering the back room, in which he would find no refuge, he tried to defend himself with a piece of wood. The defendant entered the room and fired three times, striking the victim twice and sending the victim to the floor. The defendant then walked up to the viсtim, who uttered a cri de coeur (“No, don’t”), and at point blank range fired a bullet into the victim’s head. A jury convicted the defendant of murder in the first degree and of assault and battery by means of a dangerous weapon. On the murder conviction, thе judge sentenced the defendant to a life term at the Massachusetts Correctional Institution at Walpole; on the second conviction, the judge imposed a concurrent sentence of five to ten years.
1. Denial of the defendant’s request for new counsel. The defendant argues that, in cases where an indigent defendant requests a change of appointed counsel, the trial judge is required to make a searching inquiry as to the defendant’s reasons for desiring the change.
The procedural scenario is as follows. On February 1, 1980, the defendant was indicted for the murder of Salvatore Sperlinga. Upon motion by the defendant, Mr. Frank Mar *657 ciello was appointed defense counsel as of February 11, 1980. 2 At a pretrial conference in April of 1980 Mr. Marciello represented the defendant. During the period from February, 1980, to October 6, 1980, the defendant did not indicate that he was less than pleased with his appointed counsel.
However, on October 7, 1980, the day the trial was scheduled to begin, 3 the defendant informed the judge through counsel that he wished to address the judge regarding representation of counsel. The following colloquy took place: The judge: “Well, I am not really concerned about Mr. Moran [the defendant] at this time, bеcause, quite clearly, he is not going to be afforded the opportunity to change counsel. If that is what he is looking for, the answer is: n-o, no.” The defendant: “I fired him.” The judge: “You didn’t fire anybody, sir. All right?” The defendant: “I did.” The judge: “You did? You didn’t fire him through me, sir. So let there bе no misunderstanding. You are going to trial. He is your counsel, and that is it.” The defendant: “He is not.” The judge: “He is not? Mr. Moran, he is going — this case, if the Commonwealth were ready to start today, this case would start, and he would be your counsel, like it or not.”
The judge, аfter disposing of some preliminary matters and empanelling the jury, ordered that the testimony commence the following morning. The first witness was examined and cross-examined. There was no complaint from the defendant. However, after a mоrning recess the following colloquy took place: The judge: “All right. There was an indication that you wanted to say something to me. What is it that you want to call to my attention?” The de *658 pendant: “Your Honor, I don’t want this man to represent me. I didn’t have the opportunity last night to call out. I was refused a telephone call. I am living under real tough circumstances — security. I didn’t get opportunity to contact the outside, and this is why this is at this situation now. I am very dissatisfied. I have my family who I could notify and could mаke a difference in my trial and I intend to do this.” The judge: “I think I indicated to you yesterday, sir, that I was not going to — I think you indicated yesterday that you had fired your lawyer, and I indicated: no, you had not fired your lawyer. And I am not going to discharge Mr. Marciello. So wе are just going to proceed with the trial. And you have called it to my attention that you are dissatisfied with him, and that is on the record. But we are going to proceed with the trial. Okay. Send for the jury.” Thereafter, the trial continued and the defendant nеver again mentioned any dissatisfaction with trial counsel.
After argument in this court, we remanded the case to the trial judge by an order which directed him to conduct an evidentiary hearing to determine: (1) the reason or reasons the defendаnt wanted to discharge his counsel and an evaluation of the validity of those reasons; and, (2) what criminal record of conviction of the witness Robert J. D’Onofrio, if any, could have been introduced to impeach him. 4
Pursuant to our order, the trial judge, who was authorized to grant a new trial if the ends of justice required it, conducted a hearing at which the defendant and his trial counsel testified. The judge found that there had been no conflict between counsel and the defendant. The defеndant’s sole dissatisfaction was his inability to consult ad libitum with his trial counsel. He acknowledged that this freedom was impossible because of his confinement awaiting trial. His trial counsel conferred with him on many occasions at the house of cоrrection in Billerica and at the Massachusetts Correctional Institution at Norfolk, where he *659 was later confined. His lawyer urged him to call him day or night, at his home or office, and furnished him his telephone numbers. The judge concluded that the only reason for the defendant’s desire to discharge his lawyer was his inability to see counsel as freely as he would have if he were not in custody. The defendant complained of this same problem of communication with his appellate cоunsel, who represented him at the hearing on remand. The judge did not grant a new trial.
We reaffirm our holdings in prior cases that the decision to honor a defendant’s request for change of appointed counsel is a matter left to the sound discretion of the trial judge, but after he has given the defendant the opportunity to articulate his reasons. See
Lamoureux
v.
Commonwealth,
A defendant has no constitutional right to any particular court-appointed counsel.

Commonwealth
v.
Binkiewicz,
Though we do not approve the judge’s action in this case, we are unable to discern any prejudice to the defendant, because he did not have a valid rеason to discharge his attorney. See Lamoureux v. Commonwealth, supra at 560-561.
2. Ineffective assistance of counsel. The defendant contends that he was denied his right to effective assistance of counsel due to his attorney’s failure to impeach the government’s principal witness on the basis of his criminal reсord. We hold that there was no deficiency in defense counsel’s handling of the case.
In disposing of claims of ineffective assistance of counsel, we must examine the specific circumstances of the case to see whеther “there has been serious incompetency, inefficiency, or inattention of counsel — behavior of counsel falling measurably below that which might be expected from an ordinary fallible lawyer — and, if that is found, then, typically, whether it has likely deprived the defendant of an otherwise available, substantial ground of defence.”
Commonwealth
v.
Saferian,
In this case the defendant argues that the fatal flaw in trial counsel’s conduct was his failure to impeach Robert J. D’Onofrio, the key prosecution witness, on the basis of his criminal record. There were three prior convictions which might have been admissible (possession of a controlled substance, for which he was given a six-month suspended sentence and placed on probation, and two concerned with setting up a lottery, which were placed on file).
6
Counsel decided that they did not have sufficient weight for impeachment purposes. There appear to be no other records of conviction which qualified for admission. In any event, the judge ruled that the defendant was not prejudiced and that no harm accrued to him by the attorney’s decision not to impeach by these convictions. There was no error in denying a new trial. In
Commonwealth
v.
Bernier,
*662 On the record before us we cannot say that trial counsel’s failure to introduce evidеnce concerning the chief prosecution witness’s criminal record amounted to a denial of effective assistance of counsel.
3. Review under G. L. c. 278, § 33E. We have reviewed the entire record pursuant to the mandate of G. L. c. 278, § 33E, and we deсide that the verdict of guilty of murder in the first degree is not against the law or the weight of the evidence; accordingly, we do not disturb that verdict.
Judgments affirmed.
Notes
The defendant was also convicted of possession of a firearm without a firearm identification card, but the indictment was placed on file with the defendant’s consent. Therefore, the propriety of this conviction is not an issue before us.
Commonwealth
v.
Tavares,
Mr. Marciello had also represented the defendant at the latter’s probable cause hearing in a District Court.
The assistant district attorney planned to request a continuance due to the unavailability of the pathologist who had performed the autopsy. However, the need for a continuance was obviated when the parties agreed that the autopsy report would be admitted in evidence in lieu of the pathologist’s testimony.

Faretta
v.
California,
After findings of guilty in both cases, they were placed on file. As a result of this disposition, it is doubtful that they constituted convictions admissible under G. L. c. 233, § 21, to impeach the witness.
