What does ctg mean on a airweight?

Answer 1

On an airweight Smith & Wesson firearm, or any firearm, "ctg" means cartridge. For example, "38 special ctg" or "38 spl ctg" would mean the firearm fires a 38 special cartridge. Cartridge in reference to firearms means the entire package which carries the projectile or bullet, the powder or propellant charge, and the primer which detonates and ignites the powder. The cartridge case is usually made of brass, or less commonly, steel. Many antique cartridge cases were made of copper. What many people incorrectly call the "bullet" is actually the entire cartridge package.
