Frequently Asked Questions

What is the main advantage of the Grand Power Stribog SP9A3 over the SP9A1?

The primary advantage of the SP9A3 is its delayed roller blowback action, which significantly reduces felt recoil and makes the firearm shoot much softer and flatter compared to the SP9A1's standard blowback system. This results in a more comfortable and controllable shooting experience.

How does the SP9A3's bolt differ from the SP9A1's?

The SP9A3 features a considerably lighter bolt (14.6 oz) compared to the SP9A1's heavier bolt (23.4 oz). This lighter mass, combined with the delayed roller blowback mechanism, contributes to the reduced recoil impulse and less jarring action experienced by the shooter.

What improvements have been made to the SP9A3 magazines?

The SP9A3 magazines come with improved steel feed lips and a thicker body. These enhancements are designed to address potential cracking issues that some users experienced with older magazines when left fully loaded for extended periods, increasing reliability.

What is the trigger pull weight on the Grand Power Stribog SP9A3?

The trigger pull weight on the Grand Power Stribog SP9A3 was measured at approximately 8 pounds 10.8 ounces. While this might seem heavy, the trigger is described as having minimal take-up and a crisp break, which helps to belie the pull weight.

What are the key features of the A3 Tactical brace used on the SP9A3?

The A3 Tactical brace, paired with the Gear Head Works Tailhook, is noted for its stability and sturdiness. It features a collapsible design, allowing it to be shortened for compactness, and includes QD points for sling attachment, making it a highly functional accessory.
