The Stribog SP9A3S is a semi-automatic Pistol chambered in 9MM with an 5″ Threaded Barrel, Aluminum Frame and all black finish. The Stribog SP9A3S offers the reliability and robustness of previous versions that enthusiasts, reviewers, and firearm dealers have come to love. The new Stribog SP9A3S brings a pair of fundamental improvements in the form of a semi-locked bolt with delayed action via transfer roller and non-reciprocating charging handle that remains in the front position when firing.
