May I redirect you to WW-2 history? The Thompson and the 1911 did what to how many Germans??? And with a hard ball round at that---
According to the FBI, the .45ACP is the 100% base line for stopping power and also according to them, about 70% of Police forces are so armed; here in GA the % is higher.
Interesting. Never seen the FBI quote before.
The Germans and Japanese, although on the receiving end of the .45 ACP, have never seen fit to adopt it. I wonder why?
The rest of the world's police and military forces have largely been satisfied with the performance of the 9mm. It's easier to train new recruits with, the guns generally are more reliable and hold more rounds, and the 9mm is effective if the bullet is placed right, and this is the most important aspect in any self defense shooting.
I'd say that around the world, more terrorists and criminals are shot dead by security forces armed with 9mm weapons than those of .45 ACP. Some of these countries, such as Israel, deal with the threat of terrorism every day.
I think if there was any real consensus on the issue of service caliber handgun bullet effectiveness, they would use it.Service Pistol Duty and Self-Defense Loads - M4Carbine.net Forums
