Grand Power 810091157152 SP10A3 Stribog 10mm Auto 20+1 8" Black Threaded Barrel, Black Aluminum Picatinny Rail Receiver, Rear picatinny Rail, Black Polymer Grip, Thread Protector

Description

The Grand Power Stribog SP10A3 (UPC 810091157152) is a semi-automatic 10mm Auto pistol built on Grand Power's roller-delayed blowback operating system. The roller-delayed action slows bolt velocity and reduces felt recoil compared with straight-blowback designs, which is particularly valuable in the harder-hitting 10mm Auto cartridge. 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. The 8-inch cold hammer-forged steel barrel is threaded 9/16×24 for suppressors, compensators, or other muzzle devices and ships with a thread protector installed. All controls are fully ambidextrous, including a non-reciprocating charging handle that swaps sides without tools. The SP10A3 feeds from UMP-pattern 20-round 10mm magazines.

Frequently Asked Questions

Does this pistol come with a brace?

No. This is the base pistol configuration. The 1913 Picatinny rear adapter with QD sling socket is installed and ready for aftermarket braces. The PDW Tailhook and SB Tactical SBT braces are available on other SP10A3 configurations.

What magazines does the SP10A3 accept?

The SP10A3 accepts UMP-pattern 20-round 10mm Auto magazines. It does not accept 9mm Stribog magazines, Glock magazines, or .45 ACP Stribog magazines.

How many magazines are included?

One (1) 20-round UMP-pattern 10mm magazine.

What is the thread pitch on the barrel?

The 8-inch barrel is threaded 9/16×24, the standard thread pitch for 10mm muzzle devices.

Does the roller-delayed system reduce recoil?

Yes. The roller-delayed blowback design slows bolt velocity and reduces felt recoil. This is particularly beneficial with the 10mm Auto cartridge, which produces significantly more energy than 9mm.

Can I use 9mm or .45 ACP magazines in the SP10A3?

No. The SP10A3 is chambered exclusively for 10mm Auto and uses UMP-pattern 10mm magazines. Magazines from other Stribog calibers are not interchangeable.

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.
