About Thompson/Center Arms
Thompson/Center Arms is a New Hampshire firearms maker best known for break-action, single-shot guns with interchangeable barrels. The company traces its start to 1965, when designer Warren Center joined the K.W. Thompson Tool Company of Rochester, New Hampshire, which was looking for a year-round product. Center’s basement-built break-action pistol became the Contender, announced in 1967, and the company added a Hawken-style black powder rifle in 1970, making it a major name in muzzleloading as well.
Thompson/Center holds a notable place in gun law history: in United States v. Thompson/Center Arms Co. (1992), the U.S. Supreme Court ruled that selling a pistol with a rifle conversion kit did not amount to making a short-barreled rifle under the National Firearms Act. The larger Encore followed in 1998. Smith & Wesson bought the company on January 4, 2007, moved production to Springfield, Massachusetts, after 2010 and announced it was phasing out the brand in 2021. In May 2024 former owner Gregg Ritz announced he had bought the company back and would return production to Rochester, New Hampshire.
