Claim:
A revolving firing pin system for use in a screw block assembly of a breech-loaded weapon system whose ignition is solenoid activated, said revolving firing pin system preventing an unintentional ignition of the firing pin by aligning the firing pin into a safety position when the screw block assembly's breech is not closed and properly locked, the revolving firing pin system further comprising: a spindle and a spindle cap in the screw block assembly, wherein the spindle cap defines a firing pin hole that is offset relative to a center axis of the firing pin system; a revolving firing pin assembly that rotates about said center axis to position the firing pin in alignment with the firing pin hole upon locking the screw block assembly's screw block; and wherein the firing pin has a contact finger that extends through the firing pin hole along an axis substantially parallel to said center axis; wherein the revolving firing pin is in position to strike a primer of a munition loaded in the breech-loading weapon system only when the revolving firing pin is aligned with said firing pin hole.
