SR-1 Vektor

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.

SR-1M
The SR-1M variant redesigns and modernizes the handguns frame, adds a lanyard loop behind the magazine, and enlarges the grip safety device for easier usage.

SR-1MP
The SR-1MP variant is a further modernization kit of the SR-1M which adds two additional groves onto the dust cover allowing for the user to mount a Picatinny rail adapter onto the lower dust cover section of the firearm for adding accessories such as flashlights or laser sight system. This kit also comes with a threaded barrel to allow the option of attaching a quick detach suppressor. It is currently being supplied.

SR-1PM
The SR-1PM is a fundamental redesign of the SR-1MP for blow back operation. The redesign includes a heavier slide with larger stirrations, removal of the locking wedge, and changes to the take down lever. These design changes were instituted to allow for the handgun's usage with training ammunition.
