In 1836 Colt established his Patent Arms Manufacturing Company in Paterson, N.J. The .34-caliber Paterson had a folding trigger and no loading lever. You had to carry a ramrod or change cylinders to reload. A .36-bore version became the Texas Paterson after Ranger Jack Hayes and his troops used it to swat an imposing swarm of hostile Comanches.

The panic of 1837 caused economic recession. In 1841 the Paterson plant closed. Five years later though, a visit from Texas Ranger Samuel Walker turned Colt’s attention back to revolvers. The resulting Walker Colt was a 4-1/2-pound .44, manufactured briefly at Ely Whitney’s factory. Captain Walker fell to a Mexican lance soon thereafter at the Battle of Juamantla. The Dragoon was a smaller, refined Walker .44 named after pre-Civil War cavalry. An even more compact .31 arrived in 1848, and a Pocket Model a year later. The 1851 .36 Navy earned fame in the hands of Wild Bill Hickok, who packed a pair, but it lacked the punch of the Dragoon. One grizzly hit repeatedly by .36 balls collapsed at last to a .44 Dragoon.

Despite the obvious advantages of cartridge firearms, notably Colt’s 1873 Single Action Army, the cap-and-ball revolver saw use long after their debut. Pony Express riders initially holstered two Colt Navys, 86-grain bullets atop 25 grains of black powder. Weight concerns later nixed the second pistol. Meanwhile, lawmen and outlaws shifted to bigger bullets. On August 2, 1876, Jack McCall snuck up behind Wild Bill during a card game in Deadwood and shot him in the head with a Colt .45. McCall fled west but was caught in Wyoming, returned to the Dakotas and hanged.
