On this day, February 25, 1836, American inventor Samuel Colt was awarded the patent for his innovative revolver design, formally known as the revolving-cylinder pistol. This patent, numbered 138 (later 9430X), marked the beginning of the revolver's journey to prominence in firearm history. Colt's invention enabled shooters to fire several rounds without the need to reload, significantly advancing the technology of firearms at that time. The Colt revolver eventually became renowned and a staple in America's gun culture.

Samuel Colt, a Connecticut native born in 1814, established a company to manufacture his revolver after securing the patent. His design was revolutionary for its time, offering improvements such as ease of loading and adjustments to the cylinder's weight and placement to enhance stability during firing. By the time of the American Civil War (1861-65), the Colt revolver had become one of the most famous and sought-after weapons in the world, highlighting Colt's early contributions to the arms industry and the significance of his innovations.

Despite initial slow sales and business struggles, Colt's perseverance paid off. His family's financial support was crucial in the establishment of his manufacturing company, enabling him to make refinements to his design and improve production. The revolver not only changed the landscape of personal firearms but also played a notable role in the tumultuous history of the United States, influencing both law enforcement and military practices that continue to this day.
