It is not a matter of equaling or exceeding the performance of a 45. It is a matter of using data collected from the field to determine what is required of a cartridge for the purposes of law enforcement personnel.
The report explains that 12-18" of penetration was necessary. It explains that certain 9mm loadings meet or exceed this requirement. It also explains some .40 cal ammunition does not.
It also explains that 70-80% of shots fired by law enforcement personnel in deadly force situations are misses. Which means more bullets are always better than less bullets.
It also explains that accuracy is paramount above all else. And that the lighter recoiling cartridge improves the speed and accuracy of ALL pistol shooters.
If anybody has a valid argument against any of these key points, feel free to urinate up that rope.

That's the fist I've ever heard of the .40 under performing in penetration, that was always it's strong suit...well, at least with the 180's.
