Continuity mistake: In the title sequence a Rube Goldberg machine can be seen. The error can be seen by watching the four revolvers rotating and then a single revolver firing. When you look at all four revolvers, there are hand grips in each one, but in the closeup shot of one actually firing, the hand grip is empty. You can't see it later than S5E18 because they decided to delete the frames when you can see all four revolvers, and left only closeups.
