John M Browning designed one specifically to put down the Juramentado moslem fanatics. It was called the .45 ACP COLT.
Model 1911.
Why did the USA give up the best for a ho-hum 9MM cartridge?
We gave up the 1911 as a bone to NATO countries. They gave up the 7.62 for the .556 and as a compromise we agreed to adopt the 9mm.
