The SR-1 Vektor also known as the Gyurza (Гюрза, Russian for "blunt-nosed viper") or Serdyukov SPS is a semi-automatic pistol in 9×21mm Gyurza (cartridge also used by the SR-2 Veresk submachine gun) designed for the Russian military.




Design details


The operating system is based on the Beretta 92, utilizing a dropping block. The frame is polymer and steel. While the SR-1 does not have a traditional manual safety, it is equipped with a grip safety that disengages the trigger mechanism, as well as a trigger safety to prevent fire when the trigger is not depressed. Additionally the hammer must also be placed into half-cock to engage the sear and enable double action firing.
