I watched that again, there was enough time for her to have locked the slide back when she saw him get up, there is also a click sound about the time she did it. There is about half a frame after the first shot that shows the end of the gun, slide closed.
Although they didn't show her doing it she had to have opened and locked the slide as they showed the perp getting up and dispaying the knife.
Some semi-auto pistols have a clip safety that prevents firing without the clip being inserted. I don't think any Glocks do.
My pet peeve tv/movie goof is when they rack the slide when there was one in the chamber from their previous magazine insertion, or from the last time the racked the slide needlessly.
Thank you for updating me. I'll watch carefully if I can catch it in re-runs.

I'll check the Sig 226 and get back to you tomorrow on that one.
