It was in 1902 that DWM created the famous 9
mm Parabellum cartridge, still widely in use today, to bring to its pistol a supplement of
stopping power, which was an obvious necessity to gain military markets. The pistol
underwent many structural modifications. The frame was reduced 2 mm to match the
difference between the 7.65 and the 9 mm cartridge. The first 9 mm barrels are known by
collectors as "fat barrels" for they were not tapered. The barrel length was
reduced as well to 100 mm. To get more information, refer to our book.
