Something else very seldom seen in movies and tv is misfires. They were very common in the 19th century, when fixed ammo was still new and unreliable, and in the C&B era when bad caps and wet powder were always hazards. I can think of only one misfire incident, in "Unforgiven." This was referred to the gun "snapping." A common account of a gunfight might run something like: "I fired, then snapped twice, then fired again." It was for this reason that Hickock reloaded his pistols with new charges and caps every day. When Rezin Bowie gave James his hunting knife, one of his recommendations was, "She never snaps," meaning that, unlike a firearm, the knife would always work. Later readers interpreted this to mean that the knife wouldn't break.
