Owners of the Stribog SP9A3S like that the roller-delayed system runs softer than a straight blowback gun in 9mm, and they describe recoil as manageable through extended range sessions. The threaded barrel and M-LOK handguard make it simple to add a light or foregrip without gunsmithing. A recurring complaint is trigger quality out of the box, with several owners opting to swap in an aftermarket trigger group.

For carry and field use, the tailhook brace is generally well liked for adding a stable shouldering point without the bulk of a full stock, and the non-reciprocating charging handle stays out of the way during manipulation. Some shooters find the grip angle takes a bit of adjustment coming from other 9mm platforms.

On value, having three 30-round magazines and a hard case included is seen as a strong deal compared to buying magazines separately for other PDW-style pistols. Owners also point to a growing aftermarket for Stribog handguards, braces, and internals as a plus for a gun in this price range. A few note that parts and support can be slower to source than more mainstream domestic platforms.
