 FACT: There were several errors involving the firearms used. When  Burt robs his cohorts, the gun is obviously not real, probably  rubber, because the barrel is pointed downward from the frame. If he  were to shoot at someones chest, the bullet would probably hit  below the belt. When Edmond OBrien is holding his pistol at the bad  guy, he says it is a .45, but a trained eye can see that it is  either a .32 or .380, most likely of Spanish origin. When Edmond  asks Sam Levine if he has another .45 for him, Levine says yes, but  the gun turns out to be a .38 revolver instead.
