MEMORANDUM *

Appellant Rickey D. Christian appeals his conviction for being a felon in possession of a firearm. We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we affirm.

I

The district court properly excluded time from the running of the Speedy Trial Act limitation period, 1 both with respect to pending motions and the “ends of justice” provisions of 18 U.S.C. § 3161 (h)(1)(F) and (8)(A).

II

The district court did not abuse its discretion 2 in denying Appellant a fourth new lawyer. The court’s inquiry was adequate. 3 Further, there was no showing that the degree of conflict between Appellant and his lawyer was so great that it resulted in a total lack of communication preventing an adequate defense. 4

III

We decline to consider Appellant’s claims of ineffective assistance of counsel. Claims of ineffective assistance “are generally inappropriate on direct appeal” due to the lack of a sufficient evidentiary record. 5 The record here is not sufficiently developed to permit review. Additionally, Appellant’s counsel was not so inadequate as to obviously deny him his Sixth Amendment right to counsel. 6

IV

The district court did not abuse its discretion in refusing to accept Appellant’s guilty plea. Appellant refused to engage in a plea colloquy. Therefore, the district court could not determine whether there was a factual basis for the plea. 7

*274 V

Sufficient evidence existed to support the conviction. Several witnesses identified the Appellant as the individual who pulled a firearm out of his pocket and pointed it at a man in the tavern. In addition, Appellant’s ex-wife identified the weapon as belonging to Appellant. No error, much less plain error, 8 has been shown to exist.

VI

We decline to consider Appellant’s argument that his statements to a transporting agent were involuntary and should have been suppressed. His failure to raise the argument before the trial court constitutes a waiver of the issue. Federal Rule of Criminal Procedure 12(b)(3) “requires that motions to suppress evidence be raised prior to trial,” and “failure to bring a timely suppression motion constitutes a waiver of the issue.” 9

AFFIRMED.
