Colt Peacemaker (4/20)

In the late 19th Century, shootists on both sides of the law turned to the Colt 1873 Peacemaker, chambered in the popular .45 Colt and .44-40 rounds. The single action (cock first then pull the trigger) six shooter was well balanced and fit in the hand very naturally. 

Two hundred thousand of the hoglegs were produced, originally for the US cavalry, but they quickly caught on with lawmen, cowpokes, cattle thieves and just about everyone who travelled and toughed it out in the American West. The sixgun was frequently carried alongside the Winchester 1873 lever action rifle which also chambered the .44-40 round which enabled the shooter to carry just one type of ammunition on his belt.
