First off, many "ammunition failures" have nothing to do with the bullet performance or lack thereof. If you don't hit vital areas, it doesn't matter what you're using-if you rule out tactical nukes.

Secondly, I believe that when Mas Ayoob wrote about a progression from the 147 gr 9mm to .40, he also commented that many of those departments that stayed with lighter weight (+P?) 9mm bullets stayed with the 9. Some departments went back to a lighter weight bullet and decided to stay with the 9mm.

The performance of the 125 gr JHP .357 Magnum load has demonstrated that a light for caliber, high velocity round can be extremely effective. A combination of bullet design and load development can deliver similar results in any other caliber.
