He was taken to a hospital where he was treated and is being released, his representative told the Associated Press on Sunday.
Mann sustained what his representative described as a superficial injury after a weapon accidentally discharged while holstered.
The 83-year-old director behind crime classics like Heat, Collateral and Thief has apparently been an experienced target shooter for decades, and the accident happened at a sanctioned gun range.
The award-winning director, producer and screenwriter has worked on major films since the 1980s including Manhunter, Last Of The Mohicans, and Collateral.
Mann also served as an executive producer on 1980s crime drama Miami Vice, which ran from 1984 to 1990, before directing its 2006 film adaptation
Mann continues to be quite active in Hollywood in his 80s.Â
He most recently directed the film Ferrari, with Adam Driver, and is developing a sequel to Heat, which is supposed to begin filming early next year.
