The US Army broke out it’s stored Colt single action .45 Long Colts when 126 years ago it was found the .38 Colt would not stop a doped up moslem Juramentado in the Philippines.
Only problem was the Army had started using, for a short time, the Schofield revolver in .45 short and was still issuing the “short .45” to the soldiers now with .45 colt revolvers.
It still put down the Juramentados.
That is why the army went to the .45 ACP in 1911.
Let’s bring back the 45 long Colt into service.
Or if that’s too archaic for some, 10mm full power loads in a 1911 platform.
