Grand Power 8588005808590 SP9A3S Stribog 9mm Luger 30+1 5.50" Black Threaded Barrel, M-LOK Handguard, Black Aluminum Picatinny Rail Receiver, Rear Picatinny Rail, Black Polymer Grip, Thread Protector

The Grand Power Stribog SP9A3S (UPC 8588005808590) is a compact semi-automatic 9mm Luger pistol built on Grand Power's roller-delayed blowback operating system. The "S" designation identifies the short-barrel variant with a 5-inch cold hammer-forged barrel, producing an overall length of just 13.5 inches for maximum portability. The roller-delayed action slows bolt velocity and reduces felt recoil compared with straight-blowback designs, improving control during rapid fire and making the pistol well suited for suppressed use. This configuration ships in an all-black finish with a hard-anodized aircraft-grade aluminum alloy upper receiver and black polymer lower — no brace is included, giving buyers the flexibility to add their preferred aftermarket brace or run it as a standalone pistol. All controls are fully ambidextrous, including a non-reciprocating charging handle that swaps sides without tools. The SP9A3S accepts proprietary Grand Power curved 30-round magazines — three are included in the box.

Frequently Asked Questions

Does this pistol come with a brace?
No. This is the base pistol configuration. The 1913 Picatinny rear adapter is installed and ready for aftermarket braces. The PDW Tailhook telescoping brace is available on the SP9A3S Black with Tailhook (UPC 810091152843).

What is the difference between the SP9A3S and the SP9A3?
The SP9A3S has a 5-inch barrel and 13.5-inch overall length. The SP9A3 has an 8-inch barrel and 16.69-inch overall length. Both share the same roller-delayed blowback system, proprietary magazines, and platform design. The shorter barrel trades some muzzle velocity and sight radius for maximum portability.

What magazines does the SP9A3S accept?
The SP9A3S accepts the same proprietary Grand Power curved 30-round 9mm magazines used by the SP9A3 and SP9A1. It does not accept Glock magazines.

How many magazines are included?
Three (3) 30-round proprietary Grand Power curved magazines.

What is the thread pitch on the barrel?
The 5-inch barrel is threaded 1/2×28, the standard thread pitch for 9mm muzzle devices in the United States.

Does the roller-delayed system reduce recoil?
Yes. The roller-delayed blowback design slows bolt velocity and reduces felt recoil compared with straight-blowback 9mm platforms. This also makes the SP9A3S better suited for suppressed use.

Can the charging handle be switched to the other side?
Yes. The non-reciprocating charging handle can be moved from one side to the other without tools.

Is this an NFA item?
This configuration is a pistol. No brace or stock is included. Adding a stock would require an approved Form 1 (SBR). Adding a pistol brace does not create an NFA item, but confirm current regulations with a qualified FFL or legal counsel.
