Sergeants 3 is the 1962 remake of Gunga Din starring Frank Sinatra, Dean Martin, Peter Lawford, and Sammy Davis Jr., directed by John Sturges. The film transplants the story from British India to the American West, with Sinatra, Martin and Lawford playing a trio of US Cavalry NCOs and Davis as an ex-slave longing to join them. This was the last film to star the five members of the Rat Pack, Sinatra, Martin, Lawford, Davis, and co-star Joey Bishop, prior to Sinatra's public falling out with Lawford.
The following weapons were used in the film Sergeants 3:
Calvary troops, including First Sgt. Mike Merry (Frank Sinatra), Sgt. Chip Deal (Dean Martin), and Sgt. Larry Barrett (Peter Lawford) are armed with Colt New Service revolvers mocked up to resemble Single Action Army revolvers. (Note that even if they had real SAAs, it'd still probably be anachronistic, as the setting is June 1873.)
