Frequently Asked Questions

What are the main issues reported with earlier Grand Power Stribog models?

Earlier Stribog models, particularly the SP9 A1, reportedly had issues with magazines, including the bolt hold open catch breaking. The SP9 A3 addresses some of these concerns with a different operating system and potential design improvements.

How does the Stribog SP9A3's roller-delayed system differ from an MP5?

The Stribog SP9A3's roller-delayed system is positioned above the bolt carrier, whereas the MP5's system is inline with the bolt. This difference in design can affect how the firearm handles recoil and muzzle rise, especially with heavier ammunition.

What ammunition types did the reviewer test in the Stribog SP9A3?

The reviewer tested steel-case Tula 115-grain, Maxtech 115-grain, and two types of Hornady personal defense ammunition (XTP and Black XTP). All cycled reliably through the first 200 rounds.

What are the reported accuracy limitations of the Stribog SP9A3?

At 50 yards, the Stribog SP9A3 produced groups of approximately 6 inches or larger. While sufficient for hitting targets, it's not considered a precision rifle, and accuracy can be influenced by ammunition type and shooting technique.
