Design

The .357 Magnum was designed for police, self-defense use and hunting. The objective was to create a handgun cartridge that combined good penetration, a flat trajectory and good range.

The .357 Magnum started the Magnum era of high velocity handgun ammunition.

A .357 Magnum revolver will generally accept both .357 Mag. and .38 Spl. ammunition, but a weapon designed for .38 Spl. will only accept .38 Spl. rounds, due to the longer overall length of a .357 Mag. cartridge.
