The P-83 Wanad (pl.Vanadium) is a 9 mm Polish semi-automatic pistol, chambered for the 9x18mm Makarov cartridge and designed by Ryszard Chełmicki and Marian Gryszkiewicz of the state research institute Ośrodek Badawczo-Rozwojowy in Radom. The P-83 succeeded the P-64 as the sidearm for the Polish Army and police. The P-83 is still in limited use by both the Polish police and the Polish military but it has been mostly almost completely replaced by Glock 19 and Walther P99 pistols in Police service and partially by by the indigenous WIST 94 pistol in the Polish military.
