This review of the Stribog SP45 A3 PCC by Aaron C. of Sage Dynamics highlights its roller-delayed blowback system, comparing it favorably to the UMP and MP5. The firearm is chambered in .45 ACP and accepts UMP-pattern magazines. The reviewer notes initial magazine-related reliability issues with the factory 20-rounders, recommending Global Ordinance 25-round magazines for better performance. Despite a critique of the fixed grip ergonomics, the SP45 A3 is praised for its manageable recoil, accuracy, and suppressed shooting capabilities.

Quick Summary

The Stribog SP45 A3 is a .45 ACP PCC featuring a roller-delayed blowback system, similar to an MP5, which effectively manages recoil. It accepts UMP-pattern magazines, though factory 20-rounders may require a break-in period, with Global Ordinance 25-round magazines offering more immediate reliability. The firearm demonstrates good accuracy and suppressed shooting performance.

Frequently Asked Questions

What is the operating system of the Stribog SP45 A3?

The Stribog SP45 A3 utilizes a roller-delayed blowback operating system. This system is known for its effectiveness in managing recoil, particularly with larger calibers like .45 ACP, offering a smoother shooting experience compared to direct blowback systems.

What magazines are compatible with the Stribog SP45 A3?

The Stribog SP45 A3 is compatible with UMP-pattern magazines. This includes the factory Strybog 20-round magazines, Global Ordinance 25-round magazines, and even HK-made UMP magazines, offering users a variety of options.

Does the Stribog SP45 A3 have issues with its factory magazines?

Yes, the factory 20-round Strybog magazines initially experienced reliability issues, requiring a break-in period. Switching to Global Ordinance 25-round magazines resolved feeding problems, suggesting the factory mags may need significant use to become consistently reliable.

How does the Stribog SP45 A3 handle recoil?

The roller-delayed blowback system of the Stribog SP45 A3 significantly reduces felt recoil for the .45 ACP cartridge. This makes it more controllable and allows for faster follow-up shots compared to direct blowback PCCs in the same caliber.

Is the Stribog SP45 A3 accurate?

Yes, the Stribog SP45 A3 is considered accurate. A test group of five rounds of .45 ACP 230-grain Gold Dot fired at 25 yards, bag-supported, yielded approximately a 1.5-inch group, demonstrating good precision for a PCC.
