This debate will go on forever. Long after you and I are here. Everyone will agree that shot placement is key. Acquiring the follow up shot is also as important. But not all situations are perfect. If you get a chance to fire off five rounds and only one hits, would you want that to be a .45 or a 9mm? I carry .45 and I don't have to constantly rationalize that 9mm is sufficient as long as bla bla bla...
