In Call of Duty: World at War, the .375 Plus 1 K1L-u is only usable by Pack-a-Punching the .357 Magnum on Der Riese. The result of damage is increased by 300, increasing at a rate from 1000-300 to 1000-600. The result of the fire rate remains unchanged. The magazine size remains unchanged. The appearance gains a shinier body with several areas with decorated engravings on them. Pack-a-Punching the .357 Magnum is not an ideal action, as the outcome of the .375 Plus 1 K1L-u remains somewhat unchanged.
