Double Barrel .45 Caliber Pistol The folks over at the Firearms Blog found this incredible new design created by Arsenal Firearms, who provided these photos and the video below. The AF team is clearly proud of their achievement, writing on their site that: “To commemorate the legendary Colt 1911-A1 in the Centenary by making a true industrial market-ready double barrel .45 caliber pistol. We achieved success in the brief span of 6 months, after intense and round-the-clock 3D designing, stereolithographic modeling and parts machining.” This is not an entirely new concept, and there have been many other double barrel pistols created in the past. In fact, ten years ago a Swiss armorer named Vivian Mueller cut and welded together parts of the storied Sig P210 for a similar effect. He successfully created a long slide, double barrel 9mm pistol that shot well. But the AF 2011 is the first time two pistols have been welded into one in a design that is shelf-ready and meant for sale.
