Appeal by the defendant from a judgment of the Supreme Court, Kings County (Marrus, J.), rendered April 26, 2012, convicting him of criminal possession of a weapon in the second degree, upon a jury verdict, and imposing sentence.
Ordered that the judgment is affirmed.
Viewing the evidence in the light most favorable to the People (see People v Contes, 60 NY2d 620, 621 [1983]), we find that it was legally sufficient to establish the defendant’s guilt beyond a reasonable doubt. Moreover, in fulfilling our responsibility to conduct an independent review of the weight of the evidence (see CPL 470.15 [5]; People v Danielson, 9 NY3d 342, 348-349 [2007]), we nevertheless accord great deference to the opportunity of the finder of fact to view the witnesses, hear the testimony, and observe demeanor (see People v Mateo, 2 NY3d 383, 410 [2004]; People v Bleakley, 69 NY2d 490, 495 [1987]). Upon reviewing the record here, we are satisfied that the verdict of guilt was not against the weight of the evidence (see People v Romero, 7 NY3d 633 [2006]).
The defendant’s contention that he was deprived of the effective assistance of counsel is based, in part, on matter appearing on the record and, in part, on matter outside the record and, thus, constitutes a “mixed claim” of ineffective assistance (People v Maxwell, 89 AD3d 1108, 1109 [2011]; see People v Evans, 16 NY3d 571, 575 n 2 [2011]). In this case, it is not evident from the matter appearing on the record that the defendant was deprived of the effective assistance of counsel (cf. People v Crump, 53 NY2d 824, 825 [1981]; People v Brown, 45 NY2d 852, 853-854 [1978]). Since the defendant’s claim of ineffective assistance of counsel cannot be resolved without reference to matter outside the record, a CPL 440.10 proceeding is the appropriate forum for reviewing the claim in its entirety (see People v Freeman, 93 AD3d 805, 806 [2012]; People v Maxwell, 89 AD3d at 1109).
The sentence imposed was not excessive (see People v Suitte, 90 AD2d 80 [1982]).
