Slide don't lock back in movies when empty

[Phoenixent]

The main reason you don't see slides locked to the rear when empty is for editing. When the film is edited all everyone needs is a scene that the slide locks to the rear and the gunfire is still going. You see that on screen from time to time. I have worked on sets that called for a 1911 to be thrown away after the slide locked back empty. If the script calls for the pistol slide to be lock back on an empty chamber then you will see it that way.
