 The Paterson revolver was especially decisive in the Battle of Bandera Pass, where each Ranger had 10 shots at his disposal when armed with two pistols as opposed to one.Captains Jack Hays and Samuel Walker of the Texas Rangers became major proponents of the Colt revolvers and were successful in advocating military contracts for later models such as the Walker Colt.Zachary Taylor, as a general in command of the border with Mexico, sent Captain Walker to New York in 1846 to meet with Colt and discuss improvements to the Paterson to make it more appropriate for use in battle.
