Description
Grand Power took everything people liked about the Stribog and trimmed it down. The SP9A3S runs a 5.5 inch threaded barrel that keeps the whole package remarkably compact, and with the brace folded it stows away short enough to disappear into a backpack or small case. What really sets this platform apart from the pile of blowback 9mm pistols out there is the roller-delayed action. Instead of relying on pure bolt mass to keep things closed, a transfer roller delays the bolt, which knocks down felt recoil noticeably and makes fast follow-up shots feel almost effortless for a gun this size.
Why the SP9A3S Shoots So Smooth
The non-reciprocating charging handle is another feature worth calling out. It stays locked forward while you fire, so nothing is cycling back and forth near your support hand, which matters a lot on a gun this short. Controls are fully ambidextrous, including the safety lever and magazine release, so lefties are not an afterthought here. Flip-up iron sights come installed, and the full-length top Picatinny rail takes a red dot without any fuss. M-LOK slots on the sides and a bottom rail section handle lights, lasers, or a hand stop.
Built Like a Stribog Should Be
Construction pairs an aircraft-grade aluminum upper with a polymer lower, keeping weight sensible without giving up durability. This is a Slovakian-made firearm, and the fit and finish reflect that European manufacturing pedigree. The 1/2×28 threaded muzzle ships with a protector in place and is ready for a suppressor or comp whenever you are, and the roller-delayed system runs quieter and softer suppressed than standard blowback designs.
Ready Out of the Case
Grand Power includes three curved 30-round magazines and a molded hard case, plus the SB Tactical folding brace already fitted. The Flat Dark Earth finish looks sharp and wears well. Whether you want a compact range companion, a truck gun, or a suppressor host that will not beat you up, the SP9A3S covers a lot of ground in a very small footprint.

Frequently Asked Questions
Does the Stribog SP9A3S take Glock magazines?
No, this model uses Grand Power's proprietary curved 30-round Stribog magazines, and three of them come in the case. The Glock-magazine version is a separate model called the SP9A3G. The factory mags are well regarded for reliability and spares are easy to find.
Is the SP9A3S suppressor ready?
Yes. The 5.5 inch barrel is threaded 1/2×28 and ships with a thread protector installed, so most common 9mm suppressors and muzzle devices thread right on. The roller-delayed action also runs softer and quieter suppressed than a standard blowback gun, with less gas coming back at your face.
What ammo runs best in the Grand Power Stribog SP9A3S?
The action was originally tuned around 124 grain NATO-spec loads, but current production guns include the US locker, which improves cycling with common 115 grain American range ammo. Quality brass-cased loads in either weight will keep it running happily. Like most compact 9mm platforms, it prefers consistent factory ammunition over weak steel-case bargain loads.
What makes the SP9A3S different from the original Stribog SP9A1?
Two big upgrades: the roller-delayed blowback system and the non-reciprocating charging handle. The roller delay cuts felt recoil noticeably compared to the straight blowback A1, and the charging handle stays forward during firing instead of cycling with the bolt. The S in the name means short, referring to the 5.5 inch barrel versus the 8 inch barrel on the standard A3.
