In 1992 Vektor (a small arms division of the South African DENEL corporation) produced an improved 9mm version of the Z-88 pistol (a locally produced copy of Beretta 92F), known as the Vektor SP1. A little later, Vektor also introduced a .40 S&W calibre version of the SP1, known as the SP2. Both pistols are exported to Europe and South America in several variations.
