I don't think of it in terms of how much ammo. I think of it in terms of pulling the trigger until the threat stops. That might mean a single shot. It might mean a magazine swap. Knowing my own skill level, I think that a COM hit is realistic. I'm not certain I could
count on much better than that. For me, COM means the chest, not the entire torso. I think that
most GSW recipients, unless they were just completely cranking on something, would be stopped by 3 or 4 to the chest.
Most would. Certainly not all. The reason that caliber is important, and also good bullet design, is not because a .45 is a better death ray than a 9mm, but because it will likely expand to a larger diameter than the 9mm, making a bigger hole. A bigger hole means a better chance of taking out something vital that a smaller hole might miss. That's all it means. Although I am no fan of the .380 ACP cartridge, one of those through a brain will end the fight faster than a .45 through the chest. But, I'm not going to count on making a shot to the head under that kind of pressure. That's called being a realist.
That said, even though I prefer the .45 ACP cartridge above all others, my EDC lately has been a Kahr PM9. So, to compensate, I've tried to load it with bullets that have a reputation for significant expansion with decent penetration for a 9mm. For now, that turns out to be the Corbon DPX.
