The Vis “Radom” wz 35 pistol, Invented by  Piotr Wilniewczyc and Jan Skrzypiński in 1930

The Vis “Radom” wz 35 pistol, Invented by  Piotr Wilniewczyc and Jan Skrzypiński in 1930 at the Fabryka Broni (Arms Factory) in Radom, the vis wz 35 pistol (colloquially termed the “Radom”) was to become the primary sidearm of the Polish military during World War II.  Chambered in 9mm para, the Radom drew design inspiration from John Browning Colt 1911 design.  For example the Radom uses Colts short recoil principle.  However the design has some modifications, including a triangular shaped grip for for better ergonomics and a smaller rounded hammer to make it easier to carry.Because of its size combined with the 9mm para cartridge, most of the energy of the recoil was absorbed by the pistol, allowing it to be very accurate when fired.  It was also rated to be very reliable after 6,000 rounds   A small number of .45acp models were also produced.While the Radom was to become the premier sidearm of the Polish military, only 49,000 were produced, most of them issued to the cavalry.  For the most part the Polish military had to rely on old revolvers and a hodgepodge of foreign imports.  However it was not the Polish who would capitalize on the Radom design, but their German conquerors.When the Germans invaded and occupied Poland, they also occupied their factories for the benefit of Germany. This included Fabrynka Broni Arms Factory.  As a result over 350,000 Radom pistols were produced for German use and mostly issued to German paratroopers and police.  This leads to a strange irony as the Germans produced far more Radom pistols than the Poles.  After the war production of the Radom was discontinued as Poland adopted Russian weaponry during the Cold War. -- source link
