The current production Ladysmith (by Smith and Wesson) fires .38 Special ammo, and can use any factory .38 Special ammo. Do not confuse the current Ladysmith with a tiny .22 caliber revolver made by S&W years ago.
The .38 Super cartridge is not compatible with a .38 Smith & Wesson revolver. The .38 Super is a semi-automatic cartridge primarily designed for use in 1911-style pistols, while the .38 Smith & Wesson is a revolver cartridge that is shorter and has a different case design. Using .38 Super in a .38 Smith & Wesson firearm could lead to dangerous malfunctions or damage. Always ensure you use the correct ammunition specified by the manufacturer for your firearm.
