In the Wild West never assume someone is scratching their butt.
In the Wild West, you'd more likely be shot from behind by a rascal with a vendetta than in a fast draw. Take the example of Wild Bill Hickock, executed with a bullet to the back of the head whilst leisurely playing a game of cards. Who could blame the scoundrel: would you confront a gunslinger with a mean sounding nickname?
