When Sturm, Ruger® & Co., Inc. opened for business in 1949 with a meager $50,000 investment, the company faced serious doubts from industry insiders.

But this fledgling company was guided by several well-thought-out concepts, not the least of which was founder William B. Ruger's intent to build each product "to a standard so I would want one even if it was made by our competitors." This fundamental concept, this deceptively simple touchstone of the underlying principles of innovation, quality and value, has proved so compelling that over 60 years later there is no question which company is preeminent in the American firearms industry. Ruger's rise to its present well-earned position has made it a respected company on the New York Stock Exchange since 1990.
