“Someone needs to watch an episode or two of CSI”
Really bad call using any television show.
On a recent CSI:NY the woman was captured by a thug who punched her down, took her sidearm dropped the magazine and proceeded to taunt her by popping rounds out of the magazine and saying she couldn’t do a thing about it. She picks up the discarded pistol, says most accidents happen because people forget the round in the chamber, and gut-shoots the thug.
He picks up a knife and comes after her as she loads one of the rounds dropped on the floor during the popping rounds out of the magazine incident and stuffs a round in the chamber which is accessible because THE SLIDE IS LOCKED BACK.
Fail.
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.
