The Choirboys is a 1977 crime film that follows the antics of several Los Angeles police officers both on and especially off-duty, where they host raucous parties jokingly known as "choir practice" . The film was directed by Robert Aldrich and was based on the novel of the same name by Joseph Wambaugh (The Blue Knight, The Onion Field), the former LAPD veteran turned crime novelist, but the numerous script changes from the novel caused Wambaugh to request his name be taken off the film credits. The cast included Perry King, Louis Gossett Jr. and James Woods.
The following weapons were used in the film The Choirboys:
In the film the Colt Trooper revolver is the service sidearm of LAPD officers. This is a technical inaccuracy. In the late Seventies the LAPD uniform officers carried the Smith & Wesson Model 15 with the 4" barrel.
