The Girl Hunters is a 1963 British adaptation of Mickey Spillane's 1962 novel of the same name. In an interesting twist, hard-boiled private investigator Mike Hammer is played by Spillane himself in his acting debut.
The following weapons were used in the film The Girl Hunters:
Mike Hammer (Mickey Spillane) carries a Colt M1911A1, first illegally, then legally. He describes it as a "Colt Automatic, Caliber .45." According to Mickey Spillane, "this awful Spanish gun," most likely a Star Model B, was to stand in for the Colt, but real Colt M1911s were later provided by notorious London gangster Billy Hill.

Mike Hammer pulls out his M1911A1. As Captain Pat Chambers (Scott Peters) warns later, carrying this without a permit would've been a violation of the Sullivan Act, one of the nation's oldest gun control laws still in effect.
Spillane plays with his M1911A1. Note the lack of an external extractor, which means it is not an "awful Spanish gun" (Star Model B.)
