It ships with a 20-round magazine and a brace in FDE finish. The non-reciprocating charging handle keeps the action clean during rapid fire.

Owners of the Stribog SP10A3 in 10mm consistently point to the roller-delayed blowback system as what sets it apart from simpler blowback PCCs. Recoil is noticeably softer than a direct blowback 10mm, and the non-reciprocating charging handle draws positive comments for keeping things out of the shooter's face.

The 8-inch barrel length generates debate. Those who run it as a range toy or truck gun appreciate the compact footprint with the brace folded, while others wish for a bit more velocity from the 10mm cartridge. The threaded barrel is a consistent plus for anyone who wants to add a compensator or suppressor-compatible device.

The FDE finish gets mixed feedback over time, with some owners reporting wear at contact points after extended use. Grand Power's parts support is a common concern in online threads, though most users report the pistol runs reliably out of the box on standard 10mm ammunition.
