In 1934 Mauser got it's first Military P-08 contract from the German Government. So was born the first military Mauser Luger, the "K" date of which it was estimated 10,900 were made. These were the 1934 production designation "K".
Beginning in 1935 Mauser began by marking the guns with the "G". From the "G" series beginning approximately with 930a to 5000f, (in blocks of 10,000) for approximately 54,700 guns, 700 were pulled out for the German Kriegsmarine and so marked.
