Three Days of the Condor is a 1975 post-Watergate, post-Vietnam paranoid political/espionage thriller based on the best-selling novel Six Days of the Condor and was directed by Sydney Pollack(The Yakuza, Out of Africa, The Firm). The film (now considered to be a classic of the genre) stars Robert Redford as a CIA analyst who must go on the run after finding his entire section assassinated because of a piece of sensitive information that was uncovered by him.
The following weapons were used in the film Three Days of the Condor:
Joe "Condor" Turner (Robert Redford) takes a Colt M1911 from the desk secretary after she has been killed by Joubert and "the mailman". He identifies it on the phone as a ".45 automatic." Note that when he first takes it from the desk it appears to be a wood prop.
Ingram MAC-10
"The Mailman", a hitman named William Lloyd (Hank Garrett), uses a suppressed MAC-10 during the opening hit on the CIA facility and later when attempting to kill Condor in the apartment. Condor (Robert Redford) briefly gets his hands on it twice but the mailman kicks it away each time.

Star Model B
Turner's CIA station chief S.W. Wicks (Michael Kane) requests a .45 from the CIA armorer and is given a 9 mm Star Model B, which he attaches a suppressor onto and uses during the alley shootout with Condor and to fatally shoot Sam Barber.
