When Price Buchanan is shooting at Luis Getty's partners, he runs out of ammunition, pulling the trigger several times afterwards, and you hear the hammer falling on spent shells. When he turns around, he is shot on the lower back through the wall, and gets up to move to where Hoss is. Hoss takes his gun. Luis Getty now moves to leave, and Hoss points the gun at him which no longer has any bullets. Luis Getty should have heard the gun was empty, but acts like there are still bullets in it.
