Somewhere around here I have a book with a picture of "a working cowboy's rig", a single-action Colt in a holster. The Colt has no trigger and is described as being either fanned or thumbed - neither of which sounds like a real aid to accuracy.
on the contrary , a man running slip gun was more than likely a pistolero and not a common cowpuncher
Elmer Keith experimented extensively with slip guns
I doubt "fanning" was ever used in an old west gunfight.
Fanning was a figment of some Hollywood movie maker's imagination.
Just like buscadero tie down gun rigs were.
And fast drawing... especially as a contest. May have happened once. But even that is in doubt.
Lots of Hollywood misconception...
