 Joseys two main pistols are Colt Walker 1847 Dragoon pistols. They  hold six .44 caliber ball shots. The gun features larger cylinder  chambers to allow more powder to be placed in the gun, making them  more powerful.(thus, why it was such a popular gun 20 years later.)  The Walker Colts one drawback was the weakness in the cylinder  walls. If one broke, the whole gun would blow up. This is referenced  in Clint Eastwood (qv)’s _Unforgiven (1992)_ (qv)
