Close. The Spaniards problems became ours when we beat them. The subsequent Phillipine-American War, fighting stoned Muslim Moro Tribesmen who would charge American troops, were not being stopped by the standard double-action .38 Long Army revolvers. The military drew .45 single-action Colts out of storage and directed development of a new preferably .45 semi-auto. Model of 1911 was eventually born and lasted till, don't quote me, 1985 ('88?) as the primary sidearm.
