Grand Power Stribog SP45A3 .45 ACP 8″ FDE

Description

The Grand Power Stribog SP45A3 .45 ACP 8″ FDE is a compact semi-automatic sub-pistol built on a modular aluminum and polymer receiver. It ships with an 8-inch threaded barrel, Picatinny and M-LOK attachment points, and backup flip-up iron sights out of the box. This platform is designed for shooters who want a high-capacity .45 ACP in a package that handles like a rifle but stows like a pistol.

Key Features

• 8″ Threaded Barrel — The 1:16 twist, 8-inch barrel is threaded (5/8×24) for suppressors or compensators. Why it matters: You get a longer sight radius than a standard pistol and the ability to mount a can without losing the compact profile.
• Modular Receiver with M-LOK and Picatinny — The aluminum upper has a full-length Picatinny top rail, and the polymer lower has M-LOK slots at the 3, 6, and 9 o’clock positions. Why it matters: You can mount optics, lights, or a foregrip exactly where you want them, without adapters or drilling.
• Flip-Up Backup Iron Sights — Metal, folding rear and front sights are installed from the factory. Why it matters: You have a zeroed iron-sight setup right out of the box, so you don’t have to buy aftermarket sights unless you prefer a specific type.
• .45 ACP Chambering with 13-Round Magazines — Uses proprietary double-stack magazines that hold 13 rounds. Why it matters: You get nearly double the capacity of a typical 1911 or Glock 21, in a package shorter than a carbine.
• Reciprocating Charging Handle — The non-reciprocating charging handle is located on the left side and locks back on the last round. Why it matters: It gives you positive bolt manipulation without the handle slamming forward during firing, and the bolt hold-open makes reloads quicker.

Who It’s For

This Stribog is for the shooter who wants a .45 ACP platform that bridges the gap between a full-size pistol and a rifle. It appeals to traditionalists who appreciate the .45 caliber’s proven terminal ballistics and to quality-conscious buyers who want a compact, reliable sub-pistol for range use, plinking, or home defense. If you reload .45 ACP, the 8-inch barrel gives you better velocity consistency than a 5-inch barrel, and the threaded muzzle lets you run a suppressor without losing accuracy.

Pros and Cons

• Pros: Modular rail system, factory iron sights, threaded barrel, 13-round magazine capacity, flat dark earth finish resists corrosion, reciprocating charging handle with last-round bolt hold-open, ambidextrous safety selector.
• Cons: The trigger is a bit heavy out of the box (around 7 lbs per manufacturer specs) and has noticeable creep. Some shooters will want to upgrade to a lighter trigger pack or have a gunsmith polish the sear surfaces. Also, aftermarket magazine availability is still limited compared to Glock-pattern platforms.

Comparison: Stribog SP45A3 vs. Competitors

Model	Caliber	Barrel	Capacity	Rail System	Weight	Price
Grand Power Stribog SP45A3	.45 ACP	8″ threaded	13+1	Picatinny + M-LOK	5.2 lbs	$1,459
Zev Technologies OZ9C X	9mm	4.5″ threaded	15+1	Picatinny only	1.8 lbs	$1,799
Lone Wolf Distributors G45 Clone	9mm	4.5″	17+1	Picatinny only	1.6 lbs	$899

The Stribog gives you a longer barrel and higher capacity in .45 ACP than either competitor, plus the modular rail system. The Zev and Lone Wolf options are lighter and more compact, but they’re 9mm only and lack the M-LOK attachment points. If you want .45 ACP with rifle-like accuracy and accessory mounting, the Stribog is the clear choice.
