In BALL ammo the 45 does have a substantial increase over 9mm. With modern +P+ hollow points the difference is negligible. Also the standard nato round is either 124 or 147 grain. Some 115 can be found in service. I am unaware of any 135 grain ball ammo but you seem well read on 9mm stopping power so perhaps you can shoot me a link? I am interested. BTW the top stopping round is the 357 with a mere 125 grain hollow point.

IMHO the main difference in stopping power between modern pistol cartridges is the user. The 9mm ranks a little lower because of all the poorly trained shots using it.

Also the Special Forces and others are using the 45 today.

I didn't know the military was using only 115 grain with the M-9. I made a mistake assuming military was using 135 grain bullets.

Here's a link below you can read about stopping power of pistol cartridges:
