To commemorate the 100th anniversary of the legendary Colt 1911-A1 pistol, the design team at Arsenal Firearms decided to create a true industrial 45 caliber double-barreled pistol. A team of specialists managed to do this in just 6 months of intense round-the-clock work using 3D computer simulations and stereolithography modeling.
Surprisingly, this weapon can be handled by anyone who knows how to shoot from 45 ACP (automatic Colt 45 caliber pistol). The gun is not only very pleasant to use, but also extremely accurate, it will bring a lot of pleasure to the owner.

Double Action, Double caliber, at the same time. Can’t miss it.
AF 2011 DBDC Double Barrel Double Caliber
The AF2011-A1 exhibits hit rates that are absolutely amazing for a small arms weapon: in fact, it will send all 16 bullets (8 double shots of double-bullet 45 caliber rounds) from a single-row magazine into an orange-sized target from a distance of 13.5 meters the size of a melon, from a distance of 23 meters.
The stopping power of the AF2011-A1 is huge: two bullets with a total weight of 460 grains (two bullets weigh 30 grams), hitting at a distance of 2 to 10 cm from each other (depending on the distance of the target), are capable of knocking a bull down, and all 18 bullets weighing more than 4000 grains can be sent to the target in about 3 seconds.

But the most interesting feature of the new pistol, which the manufacturers tried to achieve during the development of the project, is the interchangeability of most of the internal parts that are standard interchangeable from the 1911 issue. springs, recoil springs and recoil spring bars, magazine box and internal parts,
The AF2011-A1 (or “Twenty Eleven” as connoisseurs call it) is available with two independent triggers and a single trigger (left or right, which can be changed by the user for right-handed and left-handed operations), and with two triggers , permanently attached to each other, and with one or two triggers to choose from.
