I carried one for 7 or 8 years every day, but I never short stroked the thing -- always a full slingshot action on the slide -- more so the slide would fully engage the next round into the feed ramp.
They will come out of battery easily, though. And if there was some pressure on the slide from the perps hand, it probably failed to eject the first round, the click is either on an empty chamber, a spent casing in the chamber, or an out of battery issue. Then the officer racks the action fully and loads and fires.
BUT . . . . . . i wasn't there, and I did not read the transcript. Believeable scenario, though.
