Pistol Caliber Carbines are the latest rage for action shooting sports and self-defense classes —and why not? They can weigh less, recoil less, and cost less to shoot than their centerfire rifle brethren. But as current as the concept seems, it is not exactly a new idea. History tells us that Colt Firearms finally agreed to chamber is Single Action Army pistols in 44 WCF (also known as the 44-40) in 1877. This was a major step for the company since they had refused to offer their pistols in anything except 45 Colt to that point. That concession allowed Colt’s customers (about half the cowboys in the American West) to carry a single cartridge that would fit their pistol and their 1873 Winchester rifle. This meant they could carry one type of ammo that could be used in their revolver for close-range work and the same round in a short-barreled rifle, bringing them more capacity, greater range, and better accuracy.
