Allen's fourth 3 in the Miami Heat's game against the Milwaukee Bucks on Thursday night gave him 321 for his career, one more than the former Indiana Pacers great. Allen set the record with 8:35 to play, then added his fifth of the night a few minutes later for No. 322.
Allen's record will stand for at least a season. Kobe Bryant is third on the list with 292, but he's out for the playoffs.
Allen finished with 23 points to help the Heat beat the Bucks 104-91 for a 3-0 lead in their first-round series.
