In 1858, the Army ordered some dragoons with shoulder stocks. The pistols were to have 3 leaf rear sights on them. One stock for a pair of pistols. Both pistol's serial numbers were on the stocks. Colt also sold individual pistols with stocks on the civilian market. In the 70s, EMF sold some ASM 3rd Model Dragoons with shoulder stocks and leaf sights. They also sold an 18 inch barreled Dragoon with shoulder stock and holster. They sometimes show up on the auction sites. A couple of the pistols popped up in the past year. I picked up the pistol and shoulder stock about 2 1/2 years ago. MCB has one of the long barreled ones with holster.
