If you look at the energy of both the .45ACP and the 9mm Luger, you will find they are virtually identical.

People have a huge tendency to over inflate the .45's "stopping power", especially compared to the 9mm, with FMJ bullets. And although the energy of both rounds is basically the same, the reputation of the .45 didn't just appear out of thin air and marketing hype. There is a basis for the legend.

Other than a brain or CNS hit that shuts things down, the only thing that stops a determined attacker is loss of blood pressure to the brain. When it comes to letting the juice out, two holes are better than one (entry AND exit), and bigger holes are better than smaller ones.
