The Smith & Wesson Model 29 was the most powerful production handgun in the world when introduced in 1956, chambered in the new .44 Magnum cartridge developed in collaboration with cartridge designer Elmer Keith. Its fame exploded in 1971 when Clint Eastwood's Inspector Callahan carried it in Dirty Harry — demand immediately exceeded supply and Model 29s were backordered for years. The Model 29 is both a serious hunting handgun and an iconic piece of American popular culture.
