i know this has been debated 100 times before, but i,ve heard so much about the 45acp being the end all, in terms of one shot stop power, my question is this, since the 40s&w is pretty darn close in weight when you consider a higher grained round above 180gr of 40s&w, would'nt this round be pretty damn close if not more punchier because of the added velocity? im talking one shot knock down power, im curious as to why the 45acp is still more widely used than the 40s&w, i know bigger is better, so is the 40 always going to follow in the shadows of the 45, and im not an advocate for either, i love them both just curious?
