In the late 1920s, German Ordnance hinted at an interest in replacing the P.08 Luger pistols with a less expensive handgun design. This prompted a number of submissions from hopeful companies, including this design from the Simson company of Suhl. It is chambered for the 9x19 Parabellum cartridge (as requested by Ordnance) but is a simple blowback action.

It features a very modern and slick takedown system, but would be dropped from consideration along with other potential designs when the military opted to focus on carbines and submachine guns instead of spending money on a replacement handgun.
