History and designEdit
It is essentially a .45 ACP case, necked down to .357, resulting in a cartridge similar in form to the earlier .30 Parabellum and .30 Mauser cartridges. It was created to be a low recoil target cartridge that would function reliably with multiple bullet types, FMJ to cast lead wadcutters without the feeding problems that straight walled pistol rounds sometimes exhibit. The cartridge can be used in standard .45 ACP magazines.
Ammunition and HandloadingEdit
Brass .45 ACP cases can be resized to handload .38/45 Auto cartridges  using form and sizer dies still available from the RCBS Corporation, p/n 56468.
Nearly any 45ACP 1911 pistol can be converted to the 38/45 cartridge with a replacement barrel, from a 38 Super barrel reamed out to .38/45 dimensions, and during the rounds initial popularity, drop-in barrels were available from makers like Bar-Sto.
