For what it's worth.... I don't pretend to be an expert, but I have 5- and 6-shot capacity revolvers and didn't mean that I would leave two barrels empty. I am careful to leave the empty barrel "chambered", so if I pull the trigger, I will have 4 or 5 shots before that first click.
I also enjoy the "triple facepalm"
And the "Godzilla facepalm"
