About this product
The Grand Power Stribog SP10A3 is a compact 10mm sub pistol designed for PDW-style use and range applications. It ships with an 8-inch threaded barrel and a thread protector, a black aluminum Picatinny rail receiver, and a black polymer PDW tailhook brace and grip. The platform is described as roller-delayed blowback in the supplied materials and accepts Glock-style magazines. Its combination of capacity and compact footprint suits users seeking a high-capacity, short-barrel pistol platform for controlled, legal sporting and defensive contexts.

Key Features
- Roller-Delayed Blowback System – Why it matters: Reduces felt recoil and keeps the muzzle flat for faster follow-up shots, especially with hot 10mm loads.
- 8-Inch Threaded Barrel – Why it matters: Lets you run a suppressor or compensator without losing the compact PDW profile; the threads are protected by a factory cap.
- Tailhook Brace – Why it matters: Provides a stable cheek weld for one-handed or braced shooting, keeping you legal while maximizing control in tight spaces.
- Glock-Style Magazine Compatibility – Why it matters: Uses widely available 20-round Glock 10mm mags, so you can share ammo and mags with your sidearm.
- Full-Length Picatinny Top Rail – Why it matters: Mount any optic, red dot, or backup irons without adapters; the aluminum receiver keeps zero under hard use.
Who It's For
This is for the EDC enthusiast who wants a PDW that bridges the gap between a full-size rifle and a compact pistol. If you carry a 10mm Glock for bear country or duty, the Stribog SP10A3 gives you a shared magazine platform in a package that fits in a backpack. It's also for range shooters who want controllable power without the weight of a full rifle.
Pros & Cons
- Pro: Roller-delayed blowback makes 10mm feel like shooting .40 S&W — soft and flat.
- Pro: Tailhook brace is sturdy and collapses for storage or transport.
- Pro: Threaded barrel is standard, not an add-on.
- Con: The polymer grip texture is a bit slick with sweaty hands; an aftermarket stipple or wrap helps.
- Con: The trigger is serviceable but not match-grade — expect a 5-6 lb pull with some creep.
Comparison

|---|---|---|---|
| Caliber | 10mm | 9mm | 10mm |
| Operating System | Roller-delayed blowback | Striker-fired | Striker-fired |

The Stribog offers a longer barrel, higher capacity, and an included brace at a price that undercuts the Zev while offering more power than the Lone Wolf's 10mm pistol platform.
FAQ
Does this use standard Glock 20 magazines?
Yes, the Stribog SP10A3 accepts unmodified Glock 20/40 10mm magazines. Factory 15-rounders work, and aftermarket extended options (like the 20-rounder included) are fully compatible.
Is the Tailhook brace adjustable for length of pull?
Yes, the brace has multiple positions. The included Tailhook Mod 1C collapses and extends via a push-button release, giving you a custom fit for different body sizes or gear setups.
Can I shoot .40 S&W through this barrel?
No. The barrel is chambered specifically for 10mm Auto. Do not fire .40 S&W in a 10mm chamber — it can cause unsafe headspace and pressure issues.
Is the roller-delayed system reliable with both full-power and light 10mm loads?
Per Grand Power specs, the SP10A3 is tuned for standard-pressure 10mm ammunition. Light target loads may not cycle reliably. Stick with 180-grain or heavier factory ammo for best function.
