Vis is a 9×19mm caliber, single-action, semi-automatic pistol. Its design was inspired by American firearms inventor John Browning's 9mm "Browning GP" pistol which was completed after Browning's death by designers at Fabrique Nationale in Herstal, Belgium. Production of the Vis began at the Fabryka Broni arms factory in Radom in 1935, and was adopted as the standard handgun of the Polish Army the following year. The pistol was valued by the Germans and towards the end of the war issued to German paratroopers. The Vis is highly prized among collectors of firearms.
