The Grand Power Stribog SP10A3 is a semi-automatic pistol chambered in 10mm with a 20-round capacity. It uses a roller-delayed operation system, which reduces recoil and muzzle rise compared to a straight blowback design at this caliber.

Detailed Features 

The roller-delayed system slows the bolt carrier at the moment of firing, which keeps recoil manageable and allows faster follow-up shots. Controls, safety and magazine release, are ambidextrous, so left- and right-handed shooters can run it without modification. The threaded barrel (9/16"-24 tpi) accepts suppressors and compensators. The M-LOK rail lets you mount lights, grips, or other accessories without adding bulk to the handguard. 
 

Usage 

The 8-inch barrel and 10mm chambering make the SP10A3 well-suited to competitive shooting, home defense, and range work. Recoil is noticeably softer than you'd expect from 10mm, which helps during longer range sessions.

User feedback on the Grand Power Stribog SP10A3 10MM Tactical 8" Roller-Delayed Pistol is generally positive, with a few recurring criticisms.

Positive Feedback

Criticisms
