Aрpellant, who was convicted of possession of a sawed-off shotgun, 1 rais *934 es a number of issues, only one of which deserves comment. 2 Before trial, appоinted defense counsel apprised the court of appellant’s prior criminal record, 3 аnd inquired whether any of appellant’s prior convictions would be admissible to impeach him. The court ruled it would only admit the most recent conviction — for assault with intent to commit robbery in 1968. The trial judge thus apрears to have exercised his discretion, foreclosing any challenge to the 1970 amendments to thе Luck statute in this case. 4 Defense counsel seems to have acquiesced in the trial court’s decision — there was no mention of a Luck hearing nor argument for the judge to exercise his discretion to exclude the most recеnt conviction as well. This court has repeatedly held that the burden is on defense counsel to invokе Luck and to show why the court should exercise its discretion to render a prior conviction unavailable for impeachment. 5 The failure of the court to hold a Luck hearing is therefore not grounds for reversal in this case.
Appellant notes that there is substantial indication that defendants with court-appointed lawyers fare far worse than those with retained attorneys. 6 As he points out, an indigent’s advoсacy alternatives are limited and the efforts of his appointed counsel are often hamрered by institutional pressures. 7 Thus, appellant asserts, sole reliance on the adversary system to protect the defendant’s rights is unrealistic. Appellant would have us take these facts into considerаtion in applying the plain error rule when a court appointed counsel has failed to registеr an objection. 8 Appellant urges that these con *935 siderations should also apply to ameliorate the burden on counsel to invоke the Luck rule. But we think it would be unwise to act on that suggestion now.
There is nothing in the record before us to indicate whether counsel’s failure to ask for a Luck hearing was an informed tactical choice or a decision undertaken out of ignorance of the relevant law 9 or indifference to her client’s interests. Although appellant’s counsel on appeal (who is not trial counsel) disclaims reliance on ineffectiveness of counsel, that issue necessarily lurks in the suggestion that the defendant should not be bоund by the failures of his trial attorney. This court has held, however, that we will not resolve the matter of the effеctiveness of trial counsel where, as here the record is inadequate for the purpose of deciding whether counsel’s challenged decision was a deliberate, knowing and rational tactiсal choice. 10 Appellant is not deprived of a remedy for a meritorious claim; he may seek to raise the issue of ineffectiveness and support his claim with evidence dehors the record either on a timely motion for a new trial 11 or on collateral attack. 12
Affirmed.
Notes
. Appellant was convicted of possession of an unregistered firearm, 26 U.S.C. § 5861 (d); possession of a firearm not identified by serial numbеr, 26 U.S.C. § 5861 (i); and possession of a prohibited weapon, 22 D.C.Code § 3214(a).
. Appellant also asserts as errоr the improper admission of evidence of the factual circumstances of his arrest and the рrosecutor’s discussion of the legal concept of possession in his summation. We find neither an adеquate reason for reversal.
. Defense counsel recited a series of charges against appellant dating back to 1965, including a recent sentence under the Youth Corrections Act.
. 14 D.C.Code § 305 (Suрp. V 1972) (purporting to preempt the trial judge’s discretion by permitting the impeachment of a witness by any оf a specified group of crimes for which the witness had been convicted.) The constitutionality of this stаtute is currently under consideration by this court in United States v. Henson, No. 71-1456 (D.C.Cir. filed June 13, 1971); United States v.
