History
Adopted for the Colt Model 1892 'New Army and Navy' revolver alongside .38 Long Colt. The Army primarily issued the .38 Long Colt variant, but the .32 Long Colt version saw some Navy and Marine use. Both cartridges proved critically underpowered during the Philippine-American War (1899–1902), where Moro warriors charging under the influence of adrenaline reportedly required multiple hits to stop. The .45 Colt Single Action Army had to be reissued from storage while a replacement was developed — eventually leading to the .45 ACP and the 1911 pistol. No current commercial production.
