If the chamber is empty and the clip is full doesn’t it mean that gun didn’t cycle. Hence, jam.
No, what it means is Z was carrying with full magazine and bullet in the chamber, gun on safety, manages to get gun out and off safety in struggle, pulls trigger once, gun fires and cycles another bullet into the chamber.
Trayvon slumps, so there you sit, right by the guy you just shot, and you are holding a gun with a live round in the chamber with cops on the way. What do you do?
Drop the magazine out of the gun, jack the live round out of the chamber, and put the round into the magazine, replace magazine into the gun, and you can then hand your gun over without having to hand over a gun with a live round in tne chamber to the officer.
