Type: Double Action
Initially this gun was designed to meet Russian Army requirements for a high capacity pistol with effective range of no less than 50 meters. To achieve such characteristics, a new cartridge was developed - SP-10 (9x21) with AP steel core bullets, designed to deal with targets in bulletproof vests or hiding in cars etc (capable of near to 100% successful penetration of 30 layers of Kevlar plus up to 2.8mm titanium plate at 100 meters).
The SPS is a short recoil operated, locked breech pistol. The slide to barrel locking is achieved by the tilting locking piece, located under the barrel, much like the Walther P38 or Beretta 92. The return spring is located around the barrel. Frame is made from steel upper part and the polymer grip and the trigger guard. Slide is made of steel. Double action trigger featured automatic Glock-like trigger safety, plus internal firing pin safety and the automated grip safety. No manual safeties are provided on the gun. Until the very recent production guns, SR-1 also lacked the slide stop. The external hammer can be put on the half-cock position for increased safety. It must be noted, that the DA mode will fork only if the hammer is on half-cock. The gun is fed using steel, double stack magazines that hold 18 rounds of 9x21 mm ammo.
9x21mm ammunition now available in basic Armour Piercing form, as well as with expanding increased stopping power bullets, non-ricocheting training bullets, and some other types. The one downside of this ammo is that it is very expensive, at least now, having cost several times more than of any commercially available 9x19mm ammo.
I had the chance to inspect this gun (pictured above), during September, 2003, but not fired it yet. In my opinion, the grip is just too big for shooter with average palms. The grip safety also may play a dirty trick with the shooter, since it may not be disengaged if the gun held improperly during the stress situation, so, many FSB field operatives simply block this safety off by some sort of scotch tape. Sights are somewhat tiny. But, otherwise, the SPS is a fine and very powerful close combat weapon, that could be used as well as defensive, and as offensive weapon, especially in the room and car search scenarios, where single-hand controllability and good penetration of the round are welcome.
