This grenade consists of a die cast aluminum container which encases a steel tube containing the explosive charge. Into the steel tube is screwed a direct action nose fuze with a protruding striker head. The striker is held away from the detonator by six steel balls kept in position by a steel collar supported on three aluminum pins. The creep spring separates the striker and primer beneath which is a booster separated from the main filling by an empty air space. The black powder propelling charge is contained in a cup with a lead Styphnate primer. The grenade has grooves on the aluminum body fitting the rifling of the Kampfpistole from which it is discharged.
