Grand Power Stribog SP45A3 .45 ACP 8in 20rd Black

Description

The Grand Power Stribog SP45A3 .45 ACP 8in 20rd Black is a compact sub-pistol that punches hard with its .45 caliber punch while keeping the footprint small for everyday carry or range duty. This is a semi-automatic platform built around modularity, giving you an aluminum/polymer receiver, an 8-inch threaded barrel, and factory flip-up iron sights right out of the box. It’s designed for shooters who need a reliable, adaptable firearm that doesn’t compromise on stopping power or accessory integration. Per Grand Power specs, the Stribog family focuses on straightforward mechanical function and versatility, making this a solid pick for anyone looking to step up from 9mm without stepping up in size.

Key Features

• 8-Inch Threaded Barrel – Why it matters: Lets you attach a suppressor or compensator easily, reducing recoil and muzzle rise for faster follow-up shots in a compact package.
• Factory Flip-Up Iron Sights – Why it matters: Ready to use out of the box, with a low-profile design that stays out of the way when you mount a red dot or other optic.
• M-LOK and Picatinny Rails – Why it matters: Gives you attachment points for lights, lasers, grips, or bipods, so you can customize the setup for home defense, range use, or duty.
• .45 ACP Caliber – Why it matters: Delivers heavy-hitting terminal performance with subsonic potential, ideal for suppressed shooting or stopping threats with authority.
• Aluminum/Polymer Receiver – Why it matters: Balances durability with weight savings, keeping the gun maneuverable without sacrificing strength under recoil.

Who It’s For

This is for the EDC enthusiast who wants a sub-pistol that can double as a range toy or home defense tool. It’s for shooters who’ve maxed out 9mm and want the thump of .45 ACP in a size that fits a backpack or vehicle safe. If you’re into building out a modular platform—adding optics, lights, or a brace—this gun gives you the foundation without needing to upgrade the internals right away.

Pros & Cons

• Pro: Threaded barrel is standard, not an add-on, saving you $100+ on aftermarket parts.
• Pro: M-LOK handguard is slim and comfortable, even for smaller hands.
• Con: Factory trigger has a bit of creep—it’s serviceable for most shooters, but precision shooters will want a drop-in upgrade like a Geissele or Timney trigger.
• Pro: .45 ACP in this compact frame means less muzzle blast than a full-size pistol, but still hits hard.
• Con: Magazine capacity is 20 rounds, which is lower than some 9mm Stribog models, but that’s the trade-off for the larger caliber.

Comparison: Grand Power Stribog SP45A3 vs. Zev Technologies OZ9 vs. Lone Wolf Distributors G19

Feature	Grand Power Stribog SP45A3	Zev Technologies OZ9	Lone Wolf Distributors G19
Caliber	.45 ACP	9mm	9mm
Barrel Length	8 inches	4.5 inches	4.02 inches
Weight	4.8 lbs	1.8 lbs	1.5 lbs
Action	Direct blowback	Striker-fired	Striker-fired
Price	$1,359	$1,500+	$400+
Best For	Suppressed .45 ACP shooting, modular sub-pistol	Competition 9mm pistol	Budget-friendly 9mm EDC

The Stribog wins if you need .45 ACP in a compact, modular platform. The OZ9 is lighter and more refined for 9mm competition, while the Lone Wolf is a cheaper alternative for basic 9mm carry. But for .45 ACP sub-pistol use, the Stribog is in a class of its own.

FAQ

Does the Grand Power Stribog SP45A3 come with a brace or stock?

No, it ships as a pistol with a buffer tube that accepts standard AR-style stocks or braces. You’ll need to add your own brace (like a SB Tactical or SBA3) to comply with NFA rules if you want a stock.

What magazines does this use?

It uses proprietary 20-round magazines from Grand Power. They’re double-stack and polymer, and you can find spares on our site under the Stribog category.

Can I mount a suppressor on the 8-inch threaded barrel?

Yes, the barrel is 1/2×28 threaded, so it accepts most .45 ACP suppressors like the SilencerCo Octane 45 or Dead Air Ghost 45. Just ensure the suppressor is rated for .45 ACP.

Is this gun legal in all states?

It’s a semi-automatic pistol, so it’s legal in most states, but check local laws on magazine capacity (20 rounds may be restricted in some areas). We ship to all 50 states with compliance.

How does the trigger feel compared to a Glock?

It’s similar to a factory Glock trigger—about 5-6 lbs pull with some take-up and a clean break. It’s not match-grade, but it’s reliable for defensive use. Many owners swap to a Timney trigger for a lighter pull.
