I can't remember any of them specifically, but the sheer volume of firearm ignorance in the Lee Child books about Jack Reacher was always enough to throw me out of the stories.
If I remember right, there were multiple passages about flipping off the safeties on Glocks. There was also the time that Reacher was shot point blank in the chest with a 38 Special, but the round was so wimpy it failed to penetrate and seriously injure him. Come on.
