"Well ... yeah, sure, Dad! ... Duh! Just like a double-action revolver."
Only if you are referring to this one:
My guess is that either the reporter or Swanton or both failed to catch the nuance that was more likely referring to the dif between full auto and semi-auto. Because most certainly both the double-action revolver and the semi-auto essentially "automatically reload between shots" with "every pull of the trigger," until empty, that is.
But like I say, a doorknob has more brainpower than an alligator, so I get that it went over your head.
I sincerely doubt that any of the bikers were carrying single-action revolvers.
