Hell on Frisco Bay is an American 1955 film noir directed by Frank Tuttle and stars Alan Ladd as Steve Rollins, a former police officer who was unjustly convicted of manslaughter and returns to San Francisco after five years in prison. Now he makes his own investigation of the case in order to find who framed him.
The following weapons were used in the film Hell on Frisco Bay:
Joe Lye (Paul Stewart), henchman of mob boss Victor Amato, uses a Colt Detective Special. During Steve Rollins' (Alan Ladd) confrontation with Amato, the former cop disarms Joe from his revolver and then hands it to his friend Detective Dan Bianco (William Demarest).
When Hammy fires at Steve Rollins, Dan Bianco (William Demarest) fires back at Hammy and mortally wounds him. His revolver is seen only partially; it is possibly a Smith & Wesson Military & Police but not for sure.
Victor Amato (Edward G. Robinson) uses an M1911 in several scenes. Original movie poster show Steve Rollins holdind an M1911 but this character doesn't use this gun in the film.
When Amato leaves the office, his pistol switches to a different version of M1911 family. This pistol has different rear sights, larger ejection port (like M1911A1) and deep blue finish. Possibly it's an M1911A1 but it's hard to say for sure.
