And Mas also tends to prove it in this article.
Look at the loads/bullet weight, no matter what grain, and the FPS and you will see that this is indicitive of this idea..
Here are some paragraphs from the article:
For many years, the “Illinois State Police load” – a 115-grain standard JHP launched at some 1,300 feet per second (fps) – proved itself to be the most decisive man-stopper available. It still works great. Federal’s version of this load, the 9BPLE, is standard issue for the DeKalb County lawmen, on the tough turf that surrounds and encompasses of Atlanta, Georgia.
These guys get into so many firefights that they’ve drawn political heat for “shooting too many people.” They have proven that when they shoot people with a 115-grain JHP doing 1,300 fps out of their issue Beretta service pistols, the bad guys go down and stop trying to kill them.
Still, the faster bullets seem to be the way to go. There is much more corollary tissue damage around the wound channels with the faster 9mms, with medical examiners documenting “macerated” flesh, that is, tissue chopped up like burrito filling. You don’t see that with subsonic rounds, even though a high-tech modern 147-grain may actually expand slightly more than a lighter 9mm bullet, simply because it has “more lead to spread.”
One cartridge stands above all others in this caliber in the history of American law enforcement: the 125-grain semi-jacketed hollow point loaded to a velocity in the 1,400 fps range (from a 4-inch barrel). Some experts argue whether the wide-mouthed Federal version of this load, or the scallop-jacket Remington version that originally popularized the 125-grain .357 among cops, is the single best of the breed.
It appears that the medium-weight bullets at higher velocities are providing the best combination of penetration depth, expansion, and overall decisiveness of ending encounters. Not the 165-grain subsonic .40, the so-called “minus-P,” but 165-grain JHPs traveling at 1,140 fps and 155 grainers at about 1,200 fps. The latter has worked very well for the U.S. Border Patrol, which seems to have used mostly the Remington brand.
