Key Features

• Dual 1911 Actions – Two Colt-style 1911 actions are paired side by side in one connected frame. This gives you the proven reliability of a 1911 platform with the added firepower of two barrels per trigger pull.
• Duplex Magazine System – A specially designed duplex magazine feeds both chambers simultaneously, allowing two rounds to be fired at once or in rapid succession. This means you get double the lead downrange with each squeeze.
• Adjustable 3-Dot Sight System – The rear sight is fully adjustable for windage and elevation, while the front post is a bright white dot. This lets you dial in your point of aim for precise two-shot groups at defensive distances.
• Steel Frame & Wood Grips – The all-steel construction tames recoil and adds heft for a stable shooting platform. The walnut grip panels provide a classic, comfortable hold that feels right in the hand.
• Blued Black Finish – A traditional hot-blued finish protects the steel from rust and corrosion while giving the pistol a deep, rich appearance that looks at home in any collection.

Who It’s For

This pistol is for the experienced shooter who already owns a few 1911s and wants something that stands out at the range. It appeals to collectors who appreciate unique engineering, and to those who enjoy the novelty of a double-barrel semi-auto. It is not a beginner’s gun—it requires familiarity with the 1911 platform and a willingness to learn its quirks. If you like to be the talk of the gun club, this is your piece.

Pros & Cons

• Pros: Fires two rounds per trigger pull for increased hit probability; built on proven 1911 actions; adjustable sights for accuracy; steel frame reduces felt recoil; limited production adds collector value.
• Cons: Heavy at 55 oz compared to standard 1911s; proprietary magazines are hard to find and expensive; two-shot groups may spread more than a single barrel due to barrel convergence.

FAQ

How does the duplex magazine work?

The duplex magazine holds two separate stacks of .45 ACP rounds—one for each barrel. When you insert it into the pistol, it feeds both chambers independently. On each trigger pull, the hammer strikes both firing pins simultaneously, discharging one round from each barrel.

Is the Arsenal Dueller Prismatic reliable for self-defense?

Reliability depends on proper break-in and ammunition selection. Per American Precision Firearms, the pistol is designed for range use and collection. It can be used for defense, but the weight and dual-barrel design make it less practical than a standard 1911 for concealed carry. Most owners treat it as a range toy or safe queen.

What kind of accuracy can I expect?

With the adjustable 3-dot sights and steel frame, you can expect 3- to 4-inch groups at 25 yards when using quality factory ammunition. Barrel convergence means the two shots will land close together but not in the exact same hole. For a double-barrel pistol, that is respectable.

Are spare magazines available?

Yes, but they are proprietary and produced in limited runs by Arsenal. Expect to pay a premium—around $150–$200 per magazine. We recommend ordering a few extras when you purchase the pistol.

Does this pistol require a special holster?

Yes. Because of the double-barrel width, standard 1911 holsters will not fit. You will need a custom kydex or leather holster made specifically for the Dueller Prismatic. We can help you find one if you contact us.
