Additional visible wound damage? WTF is that and what does it have to do with lethality? 12ga. #7 birdshot makes an awesomely gruesome "visible wound" when compared to 12ga. #00 Buckshot, but I don't see anyone but the village idiot claiming it's a better man stopper. It all comes down to poking a hole in human flesh, and whether you believe it or not all service caliber handguns do about the same (mediocre) job of poking said holes. There is no magic bullet/caliber, deal with it and train accordingly. Wanna kill these ads? We can help!
