As the construction is identical, 38 Special Ammo can be used in handguns chambered for 357 Magnum. 38 Short Colt and 38 Long Colt can be fired safely from handguns chambered for 38 Special. The straight walls of the cartridge, rim’s head spacing, accessibility of earlier fired cases, and the compatibility with 357 Magnum firearms made it much popular.
