Features The Stribog SP9A3 offers the reliability and robustness of previous versions that enthusiasts, reviewers, and firearm dealers have come to love. The new Stribog SP9A3 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. The Stribog is manufactured using a hard anodized aircraft grade aluminum alloy, which makes it lightweight, but highly durable. The manufacture of this pistol just adds to Grand Power’s reputation of using high quality and precision manufacturing techniques. Designed with versatility and customization in mind, the Stribog has top and bottom picatinny rails, and M-LOK mounts on each side of the handguard. It also comes with a threaded barrel with included thread protector, and flip up front and rear sights.
