I'm writing a historical novel which features the 4th Cavalry in the Philippines from 1898-1901. I know the Colt 1911 was developed as a result of the weak .38 issued to the army during that war, but what I need help with is info on what sidearm the cavalry, rather than the army, was using at that time. Was the cavalry also issued the .38? Or did they continue using Colt Peacemakers? Any help would be deeply appreciated. I like to be accurate with details like this in a work of fiction.
