A cartridge case especially for firing in handguns has a primer receiving pocket provided in the bottom or rear portion as a cylindrical recess, into the top of which at least one flash hole terminates, a primer cap mounted flush in the primer receiving pocket including a cup-shaped capsule having a capsule bottom and a cylindrical side wall, and with a primer charge and an anvil located inside the capsule. To improve gas tightness in the direction of the breech of the gun, especially in the use of pollutant-free primer charges, the primer receiving pocket is provided in the vicinity of a side wall of the capsule with an annular circumferential expansion zone, so that the anvil has room to deflect after ignition of the primer charge and expansion of the capsule.
