The first step in that process was to withdraw from issue the .38 caliber (double action?) revolvers then in use and replace them with Colt Single-Action Army 1873 .45's that had been in storage. My understanding is that the Moros would tie strips of cloth very tightly around their arms as legs, almost to the point of cutting off circulation, like a tourniquet, before battle. That way, if they were hit in the arm or leg, they wouldn't bleed out. It would take a hit to the central nervous system to take them completely out of action. Modern non-Genevea-approved bullets are far more effective, but for defense of self and family I'm still more comfortable with a round that starts with a "4" rather than a "3" (which would include the 9mm).
Having been born a few years after that insurrection (in spite of what my children believe), I have only read accounts of the action.
