Goof: When Stokes and Crawford confront Basderic in the parking garage, Stokes takes Basderic's pistol, removes the magazine and hands both to Crawford. Crawford puts the magazine in his pocket and holds the pistol in his hand. When they release Basderic, Crawford inserts the switched magazine with blank rounds into the pistol and hands it back to Basderic.
Later, at his house, Basderic fires three rounds at Sidle. First problem is that when you remove a magazine from an automatic pistol, there is still one live round in the chamber and the first shot would have struck Sidle. Secondly, Basderic fires three quick rounds. Blank cartridges cannot generate the pressure needed to cycle the slide unless the weapon is fitted with a special device.
The first live round would have ejected and activated the slide, but the second blank round would not making it impossible to fire another blank round.
