Manufactured concurrently with the military contract P.38, the Zero Series was made on the same assembly lines (and often used military inspected components), intended for commercial sale both in Germany and abroad, with an estimated production total of less than 2000. Blade front and notch rear sights, with a full blue finish and ribbed grips. Matching numbers are present in the "commercial" pattern, with the slide number on top (obscured by the barrel when the breech is closed) and the frame number on the right side, with the slide marked "P.38" and "ac45" on the left side and one each of the "eagle/359" and "eagle/swastika" inspection marks on the right.
