Is that why in "Cemetery Without Crosses", Robert Hossein puts a leather glove on the hand he doesn't shoot with? Curiously you never see him "fanning" the gun in any case.If I remember correctly, Hossein said in the interview that it was a little quirky touch he added, although he never really mentioned a purpose for it. I'll have to watch the interview again to check.
Why is there no re-coil when eastwood fans the gun?
These guys can't have regular jobs though because they probably have to practice this 10 hrs a day!
