Yeah, I just finished a Faye Kellerman book, "Serpent's Tooth", I believe it was. My wife passed it to me. She starts out talking about how the killer used a double action pistol automatic pistol. But the detectives figured there were too many rounds. No one could fire that many in such a short time even from a "double automatic". This line of crap continues throughout the entire book.
Know what? I know it's fiction. I know a lot of folks have no gun knowlege. But when an author writes this kind of crap just because they know that most of their audience won't know the difference, well that is just plain laziness and poor workmanship. That author hasn't done their research, indeed they haven't done their job, and I won't read any more of their stuff.
