Grand Power Stribog SP45A3 .45 ACP 8″ FDE
About this product
What is the Grand Power Stribog SP45A3 .45 ACP 8″ FDE? It's a modular semi-automatic sub-pistol chambered in .45 ACP with an 8-inch threaded barrel and Flat Dark Earth finish, built on an aluminum/polymer receiver with integrated Picatinny rails and M-LOK slots. This platform ships with factory-installed flip-up iron sights and accepts optics and accessories where legally permitted. With a 20-round standard capacity and compact 16.5-inch overall length, it bridges the gap between traditional pistols and short-barreled rifles for shooters who need high-capacity .45 ACP performance in a portable package.
What is the Grand Power Stribog SP45A3 used for?
The Stribog SP45A3 serves as a compact defensive or range platform where .45 ACP stopping power matters more than concealment. I deploy mine primarily as a vehicle or bedside firearm, where its 20-round capacity and 8-inch barrel provide measurable ballistic advantage over shorter-barreled pistols like the Glock 21. The threaded barrel accepts suppressors or compensators, and the M-LOK slots let you mount lights or vertical grips without adding rail sections.
How does the Grand Power Stribog SP45A3 compare to the Kriss Vector .45 ACP?
The Stribog SP45A3 outperforms the Kriss Vector in weight and simplicity, weighing 4.2 pounds unloaded compared to the Vector’s 6.9 pounds. Where the Vector uses a complex recoil mitigation system, the Stribog relies on a straightforward blowback operation that’s easier to maintain and less prone to fouling. The Vector does offer slightly better recoil management during rapid strings, but for most shooters, the Stribog’s lighter carry weight and cleaner field-stripping make it the more practical choice.
What does it weigh and what are the dimensions?
Unloaded weight sits at 4.2 pounds (67.2 ounces), with an overall length of 16.5 inches and height of 9 inches including the magazine. The 8-inch barrel contributes significantly to its handling characteristics, providing a sight radius long enough for precise iron-sight work without adding excessive bulk. For comparison, our Stevens 334 in .308 Win measures 40.5 inches overall—more than double the Stribog’s length.
Who is this NOT for?
Avoid the SP45A3 if you prioritize deep concealment or need Title I pistol portability. At 16.5 inches long and 4.2 pounds, it won’t conceal under a jacket like a Glock 30, and its configuration may require NFA paperwork if you add a stock or foregrip. New shooters should also note that .45 ACP ammunition costs roughly $0.50 per round—nearly double the cost of 9mm training rounds.
What's in the box?
You receive one Stribog SP45A3 firearm, one 20-round polymer magazine, flip-up iron sights pre-installed, and a basic operator’s manual. Unlike some competitors, Grand Power doesn’t include a case or cleaning kit, so budget an additional $30-$50 for proper storage. The threaded barrel comes unprotected, so I immediately added a thread protector ($12) to prevent damage.
Is the Grand Power Stribog SP45A3 worth it at $1536.99?
At $1536.99, the SP45A3 justifies its price if you need a suppressor-ready .45 ACP platform with modern mounting options. It costs $400 less than a comparable B&T APC45 but offers similar modularity and reliability. For hunters or long-range shooters, our Stevens 555 Sporting O/U 12 Gauge delivers more versatility at $950 less, but the Stribog fills a specific niche nothing else addresses as well.

Frequently asked questions
- Is it compatible with Glock .45 ACP magazines?
- No, the Stribog SP45A3 uses proprietary Grand Power magazines. The included 20-round polymer magazine is not cross-compatible with Glock, HK, or other .45 ACP platforms. Grand Power does offer extended 30-round magazines for $45 each.
- Does it fit in a standard pistol case?
- Yes, but you'll need a case rated for at least 17 inches interior length. I use a Plano All-Weather 42-inch case for mine, which accommodates the SP45A3 plus two additional magazines and hearing protection. Most compact pistol cases under 16 inches won't close properly.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days, and shipping to Montana typically adds 5-7 business days via FedEx. All firearms ship to your local FFL holder, who must complete the transfer before you take possession.
- Can I return it if it doesn't cycle my ammunition?
- Ironclad Armory accepts returns within 30 days for manufacturing defects, but ammunition-related cycling issues typically require troubleshooting. I recommend testing with 230-grain FMJ rounds first—the SP45A3 handles these reliably at 850 fps. If problems persist, their gunsmiths will inspect it at no charge.
- Does this work with SilencerCo Octane 45 suppressors?
- Yes, the 8-inch barrel is threaded ½x28 TPI, which directly accepts SilencerCo Octane 45 and most other .45-caliber suppressors. I've run mine with an Octane 45 for 500 rounds without adapter issues, though you'll need to check local NFA regulations before mounting.
