Designed in 1934, the .357 Magnum cartridge is the bigger, badder brother of its predecessor, the .38 Special. In the years since its development, its power and versatility have kept it popular with both law enforcement officers and private citizens.

SOME OF THE GREATEST combat cartridges ever devised that are still in common use are 100 years old, and so are the platforms that fire them. The ones that come to mind are the .38 Special (1898), the 9mm Luger (1901), the .45 ACP (1904), and the youngster of them all, the .357 Magnum.
