It's not describing an automatic weapon - it's describing how the chamber reloads after each shot without having to do a hard trigger pull or




the hammer or manipulate the slide.
That was not why the case was overturned - or changed from murder to culpable homicide. It was reduced because there was evidence that the accused really believed he was under attack (even though the deceased wasnt armed). He was still found
guilty of culpable homicide though because the accused should have known that firing 3 shots instead of 1 would have been excessive even if it was an actual self defense situation.
