The .38-45 ACP cartridge is a modified version of the .45 ACP cartridge, which was developed by John Browning in 1904. The .38-45 ACP was created by necking down the .45 ACP case to accept a .357 inch (9.1 mm) bullet.The .38-45 ACP cartridge was developed in the early 1900s as an experimental round for the US military. It was intended to be a replacement for the .38 Long Colt cartridge, which was deemed inadequate in combat.The .38-45 ACP cartridge was tested extensively, but it was ultimately rejected in favor of the .45 ACP cartridge, which was considered to be more reliable and effective. Today, the .38-45 ACP cartridge is considered to be a historical curiosity and is not commonly used or available.
