Cartridge developed around 1869 for use in both the Werder M69 Pistol as well as the Werder Carbine developed by Johann Ludwig Werder and based on his rifle design from 1868. It used a falling block design and was one of the first center-fire handguns to be adopted by a European military power. It had a high rate of fire and was therefore also called the “Bavarian Lightning Pistol”. I was a cumbersome weapon being too heavy as a handgun on the one hand and not effective enough in a carbine.
