About this product
The Grand Power Stribog SP10A3 10mm — 8in Threaded Barrel, 20rd is a compact 10mm semi-automatic pistol-caliber carbine with an 8-inch threaded barrel and factory-installed SB Tactical folding brace built for suppressor compatibility and modular accessory mounting. It combines an aircraft-grade aluminum upper receiver with a polymer lower for a 5.2 lb unloaded weight while maintaining full-power 10mm ballistics in a package shorter than most AR-pattern pistols.
What is the Grand Power Stribog SP10A3 10mm used for?
This platform serves as a compact-duty and suppressor-host firearm for 10mm enthusiasts seeking reduced muzzle flip and improved terminal ballistics over handguns. The 8-inch barrel provides approximately 200-250 fps velocity gain over 5-inch pistol barrels while remaining compact enough for vehicle deployment, and the threaded 9/16×24 barrel accepts most common 10mm suppressors without adapters.
How does the Grand Power Stribog SP10A3 compare to the CMMG Banshee 10mm?
The Stribog SP10A3 offers superior out-of-box suppressor readiness and lower cost compared to CMMG's radial-delay blowback system. Where the CMMG Banshee 10mm requires additional financial investment to achieve similar suppressor compatibility, the Stribog ships with proper threading and comes in at nearly $400 less than comparable Banshee configurations while maintaining reliable blowback operation with full-power 10mm loads.
What does it weigh and what are the dimensions?
This firearm measures 19.5 inches extended with a 6.7-inch collapsed length when folded, weighing 5.2 pounds unloaded. The 8-inch cold-hammer-forged barrel provides optimal length for 10mm velocity retention while keeping overall package dimensions below 20 inches for storage in standard tactical bags, and the aluminum upper contributes to weight distribution that reduces felt recoil by approximately 15% compared to all-polymer alternatives.
Who is this NOT for?
This firearm is ill-suited for beginners or those seeking traditional rifle platforms due to its specialized 10mm chambering and pistol brace configuration. The 10mm ammunition costs approximately 40% more than 9mm, making practice sessions economically prohibitive for casual shooters, and the folding brace requires understanding of ATF regulations regarding pistol versus rifle classifications that might confuse new owners.
What's in the box?
The package includes one 20-round polymer magazine, SB Tactical SBT folding pistol brace pre-installed, factory flip-up iron sights, and a 9/16×24 thread protector. Unlike some competitors that ship with single magazines or missing accessories, Grand Power provides complete out-of-box functionality including the essential thread protector that prevents barrel damage during transport and storage.
Is the Grand Power Stribog SP10A3 worth it at $1586.99?
At this price point, the SP10A3 represents solid value for dedicated 10mm users seeking a suppressor-ready platform without aftermarket modifications. Compared to building a similar AR-9 platform with equivalent features which typically runs $1800-2200, the Stribog delivers immediate suppressor compatibility and reliable function with various 10mm loads while including the essential brace system that often adds $200-300 to competitor packages. For hunters considering our Stevens 334 in .308 Win but wanting more compact performance, this fills a different tactical niche.

Frequently asked questions
- Is it compatible with Glock 20 magazines?
- No, the Stribog SP10A3 uses proprietary 20-round magazines specifically designed for its feed geometry. While some aftermarket options exist, they require testing for reliability unlike the proven Stevens 334 system that uses standardized detachable box magazines.
- Does it fit in a standard pistol case?
- When folded to its 6.7-inch collapsed length, it fits most 18-inch tactical cases but requires careful positioning due to the 8-inch barrel profile. For comparison, our <a href="/products/stevens-555-sprtng-ovr-undr-20ga-cmp">Stevens 555 Compact shotgun</a> measures 26 inches overall and fits standard cases more easily.
- How long does shipping take to Montana?
- Firearms shipping to Bozeman typically take 3-5 business days via FedEx Priority with signature confirmation required upon delivery. All shipments include tracking numbers emailed within 2 hours of processing.
- Can I return it if it doesn't cycle properly?
- Returns are accepted within 30 days for mechanical issues, but firearms must undergo inspection by our certified armorers before approval. Most cycling issues with 10mm platforms involve ammunition selection rather than mechanical defects.
- Does this work with SilencerCo Omega 45 suppressors?
- Yes, the 9/16×24 threading directly accommodates SilencerCo Omega 45 models without adapters, though we recommend checking suppressor weight as the 8-inch barrel may require additional support for optimal alignment.
