Walker is best known as the co-inventor of the famous Walker Colt revolver, along with arms manufacturer Samuel Colt. Walker is said to have self-funded a trip to New York City to meet with Colt and proposed to him the concept of a weapon based on the then-popular five-shot Colt Paterson revolver, with many enhancements such as adding a sixth round, being powerful enough to kill either a man or a horse with a single shot and quicker to reload.

Colt's firearms company was no longer in business, but the large order allowed Colt to establish a new company. He hired Eli Whitney Junior, already in the arms business, to make his new revolvers. Colt asked Samuel Walker, who happened to be temporarily stationed in Washington, to help him with the design.

Colt used his prototype and Walker's improvements to create a new design. Whitney produced the first thousand-piece order, known as the Colt Walker. The company then received an order for an additional one thousand more. Colt's share of the profits was $10.

By 1847, the new revolver was available. The United States Army's mounted rifle companies were issued them, and they proved extremely effective.
