As stated the 9mm/45ACP is inadequate for deer except under unusual circunstances.

I agree that a heavy caliber handgun is better for whitetail and general woods carry due to its better "stopping power", though puny by rifle standards.
I like carrying the 45 colt loaded hot.

Interesting that studies between 9mm and 45ACP show no different effectiveness between the calibers with both requiring multiple shots to neutralize human opponents.The popular Marshall "stopping" studies are flawed and not objectively quantified enough for all variables present in a scientific fashion..
