So, I had always been a .45acp or .357 mag man when it came to SD. In theory I accepted that .38 special was the smallest SD round that was acceptable. But really, for my purposes I shied away from even .40 S&W. But then in my normal internet perusings I ran into some writing by a guy named Chuck Hawks. And he mentioned studies done by some fellows by the name of Marshall and Sanow. Who I have also heard you mention. A long with some other things I've seen, I'm all topsy-turvy now. Would you say that despite all of the foo-fa-rah, that statistics support that you should consider yourself well heeled if you are carrying .38 special, 9x19, .40 S&W, .45 acp, .357 mag as long as you are loading with the proper defense round in the correct firearm? And if that is true what would you say are the arguments for choosing the .45 acp over the other rounds when you are sacrificing size of firearm as well as capacity? I'm not asking for you to prove to me what cartridge is best. I know that can't be done definitively. Just looking for a few thoughts on the matter.
