Why is there such a disparity when people talk about the best defensive carry ammo? No one seems to have a lock on the best. Seems that with as much science and research as we have today, we should have a number 1,2,3 & 4. But every where you look, the 9mm is better, the 357 Sig is better, the 40 S&W is better, the 45 ACP is better, the 10 mm is better, ad naseum.
The other argument is...there is no difference, they all suck as defensive rounds. I drives me crazy to look at all the info and still not be able to come to some logical conclusion.
Anything new in this age old argument, or am I right on both counts?
