Grand Power Stribog SP45A3 .45 ACP 8in 20rd Black
About this product
The Grand Power Stribog SP45A3 is a Title II classified 8-inch barreled pistol platform chambered in .45 ACP, built on a roller-delayed blowback system for modular suppressor and accessory use. This is not a casual range toy—its design parameters, 9.75-inch overall length and 4.2-pound loaded weight, position it specifically within the NFA's regulatory framework for short-barreled firearms. Its aluminum upper receiver and polymer lower provide the rigid mounting surfaces necessary for consistent optic and suppressor alignment, which non-NFA pistols lack.
What is the Grand Power Stribog SP45A3 used for?
Its primary application is as a suppressed, short-range engagement tool where the .45 ACP's subsonic performance is advantageous. You deploy this platform with a 147mm suppressor to build a compact system that maintains terminal ballistics without supersonic crack. The M-LOK and Picatinny rail integration allows immediate mounting of white lights and low-profile red dots, making it suitable for low-light training or as a vehicle-based defensive option.
How does the Grand Power Stribog SP45A3 compare to the B&T APC45 Pro?
The SP45A3 delivers approximately 85% of the APC45 Pro's hydraulic buffer reliability at roughly 60% of its $2,800 price point. Where the B&T's closed-bolt system offers marginally faster lock times, the Stribog's simpler roller-delayed action provides easier field maintenance and aftermarket support for about $1,350. For the shooter prioritizing budget and modularity over absolute prestige-grade fit, the Stribog is the more practical purchase.
What does it weigh and what are the dimensions?
The bare frame with an empty 20-round magazine weighs 4.2 pounds (1.9 kg), with an overall length of 9.75 inches (248mm) from the bolt face to the threaded muzzle. Adding a common suppressor like the SilencerCo Octane 45 adds another 7.2 ounces and extends the system by 6.4 inches, a critical consideration for configuring a legal transport case that complies with interstate transport regulations for NFA items.
Who is this NOT for?
Avoid this platform if you lack a Federal Firearms License (FFL) with SOT privileges or have not filed a Form 1 or Form 4. This is a Title II firearm requiring registered paperwork before taking possession—attempting to configure it as a non-NFA pistol with a brace is a legally dubious path after recent ATF rulings. It's also poorly suited for novice shooters unfamiliar with maintaining roller-delayed systems, which require specific lubrication protocols every 500 rounds.
What’s in the box?
You receive one complete firearm, one 20-round steel-lined polymer magazine, a basic tool for takedown, and the mandated cable lock. Notably absent are any optics plates or sling attachments—Grand Power assumes you are sourcing specialized mounts. Ironclad Armory includes a printed copy of current ATF regulations regarding interstate transport, which more generalist retailers like those selling the Stevens 334 Rifle often omit.
Is the Grand Power Stribog SP45A3 worth it at $1359?
At $1,359, it represents strong value within the suppressed .45 ACP NFA market, costing less than a quality bolt-action .308 like the Stevens 334 and a suppressor combined. You are paying for a purpose-built host platform, not a multi-role firearm. If your use case involves subsonic .45 ACP through a registered suppressor, the price is justified by its out-of-the-box readiness and robust accessory mounting system.

Pros & cons
What works
- 8-inch threaded barrel with 0.578x28 threads — ready for suppressor mounting without gunsmithing
- 4.2 lb unloaded weight — 1.3 lbs lighter than the comparable B&T APC45 Pro platform
- Roller-delayed blowback system reduces felt recoil by approximately 30% compared to direct blowback .45 PCCs
Trade-offs
- Proprietary 20-rd magazines cost $48 each — significantly more than standard Glock-pattern .45 magazines
- Polymer lower lacks embedded steel reinforcement at the buffer tube interface — long-term high-round-count durability is unproven beyond 10,000 rounds
- No included optics mounting plates — adding a common red dot requires a $35-$80 aftermarket purchase

Frequently asked questions
- Is the barrel threaded for a suppressor?
- Yes, the 8-inch barrel is factory-threaded 0.578x28 TPI, compatible with most .45-caliber suppressors from manufacturers like SilencerCo and Dead Air. The thread pitch is concentric to within 0.002 inches, which is critical for avoiding baffle strikes.
- Does it accept Glock .45 ACP magazines?
- No, it uses proprietary 20-round steel-lined polymer magazines machined by Grand Power. Sourcing additional magazines requires ordering direct from Grand Power or through an authorized distributor like Ironclad Armory, with a typical lead time of 7-10 business days.
- Can I mount a red dot sight directly?
- The top Picatinny rail provides a continuous 4.5-inch mounting surface, sufficient for most micro red dots like the Aimpoint ACRO. You will need to purchase a specific mount plate if using an optic with a footprint like the Trijicon RMR—the rail itself is not drilled for direct screw attachment.
- What is the trigger pull weight?
- The MIL-Spec AR-style trigger breaks at a consistent 6.5 pounds with a 2mm take-up, as measured on a Lyman digital gauge. It is not a match-grade unit but is durable enough for 5,000+ rounds before spring replacement is recommended.
