Goes on to illustrate the brutal effectiveness of a mousegun caliber in the hands of someone who is determined and sober.
Rachen, no disrespect, but what happens in a TV series is "fiction". Antique guns and reproductions of them, even though we are all enthusiasts, are not to be weapons of choice (if you have a choice). Having to aim for the head is hard in most aggressive situations. That's why a larger caliber aimed at center mass is thought to be the best practice in real situations. That said, a .31 BP pistol is many times better than a sharp stick or pepper spray.
