Thompson Center Arms: History, Firearms, and the Legacy of Innovation

For more than half a century, Thompson Center Arms has stood as one of the most innovative names in American firearms manufacturing. From the groundbreaking introduction of the Contender pistol in the 1960s to the company’s pivotal role in reviving muzzleloading traditions in the 1970s, Thompson Center has consistently redefined versatility and craftsmanship. Its legacy spans not only iconic firearms but also a landmark Supreme Court case, corporate acquisitions, and a recent return to independent ownership—bringing the brand full circle to its New Hampshire roots. This is the story of a company whose products and history continue to shape the culture of shooting sports and hunting across the United States.

Thompson Center Arms: Back in Familiar Hands

For generations, the name Thompson Center Arms has carried weight with hunters, shooters, and collectors alike. Known for innovation, American-made craftsmanship, and unmatched versatility, the brand carved out a unique place in the firearms world. From the original Contender pistols to the iconic Hawken muzzleloaders and the adaptable Encore platform, Thompson/Center built tools that delivered accuracy, dependability, and adaptability in the field.

But while its products earned legendary status, the company’s journey has not always been smooth. Ownership changes, facility moves, and shifting priorities caused the brand to lose visibility in the marketplace. That changed in late 2024, when former president and CEO Gregg Ritz, who had once overseen Thompson Center’s growth and its integration into Smith & Wesson, brought the company back under his ownership. For Ritz, this was more than another business deal. It was a homecoming and a promise to rebuild the brand’s reputation, restore its product lineup, and reconnect with loyal customers.

Thompson Contender – From Workshop to Legacy Brand

The Thompson Center story began in 1965, when gunsmith Warren Center developed a break-action single-shot pistol in his basement. The design quickly caught the attention of K.W. Thompson Tool Company, which was looking for a year-round product to build in Rochester, New Hampshire. By 1967, the Thompson Contender pistol was introduced to the public. It offered shooters a huge advantage with its interchangeable barrels, making it possible to switch calibers on a single frame.

That innovation set the tone. The Hawken muzzleloader, launched in 1970, became one of the most recognized black powder rifles in North America and helped fuel a surge in muzzleloader hunting. By the 1990s, Thompson Center had expanded into bolt-action rifles, inline muzzleloaders, and larger break-action platforms. The company had earned a reputation for giving hunters more choices in one firearm.

Challenges and Change and Closing its Doors

The company’s resilience was tested in 1997, when a fire destroyed three of its Rochester NH, buildings. Instead of closing its doors, Thompson Center rebuilt and introduced the Encore rifle platform later that year. The Encore was bigger and more robust than the Contender, and it could handle centerfire cartridges, muzzleloader barrels, and shotguns all on one frame. It became a hallmark of T/C’s ingenuity and toughness.

In 2007, Smith & Wesson purchased the company for $102 million, with Gregg Ritz staying on to lead the transition. Production eventually moved to Springfield, Massachusetts, in 2010, and many longtime employees did not relocate. While Smith & Wesson continued producing some T/C models for a time, the brand slowly lost ground until 2021, when the company announced it would phase out Thompson Center altogether.

Greg Ritz Brings Thompson Center Arms Back Home

Gregg Ritz’s decision to reacquire Thompson Center Arms in 2024 was both professional and personal. Having guided the company once before, he understood the strength of its heritage and the loyalty of its customers. Under his leadership, production has returned to Rochester, New Hampshire, with upgraded facilities and some original employees returning to work.

Ritz’s vision is straightforward: revive the classics, innovate for the future, and restore customer trust. The relaunch plan includes bringing back the Encore in 2025 with modern upgrades, followed by the Thompson Contender and Triumph muzzleloader. A new Icon bolt-action rifle is also planned before the end of the year, along with expanded barrels, stocks, and accessories. Each firearm will carry a lifetime warranty, sending a clear message that the company will stand behind its products.

Where the Company Is Headed Today

Looking ahead to 2026, Thompson Center plans to maintain a balance between honoring its heritage and driving forward with new designs. That means more old favorites returning to production, along with new calibers, upgraded ergonomics, and features that reflect modern hunting and shooting trends.

Ritz emphasizes that the revival is not about quick gains but about building a sustainable future. “We’re making decisions for the long haul,” he explained. “That’s why we’re hiring skilled craftspeople, investing in R&D, and keeping all of our manufacturing right here in the USA.”

Legacy Influencers and the Brand’s Rise

Part of Thompson/Center’s success over the years came from high-profile promotion by respected figures in the hunting industry. Endorsements from personalities like Jim Shockey, Larry Weishuhn, and Michael Waddell further solidified the brand’s credibility, and clever media sponsorships like the “You Call the Shots” segment on North American Hunter kept it top-of-mind for sportsmen.

Innovations That Defined the Brand

The hallmarks of Thompson Center’s success have always been versatility and quality. The Thompson Contender pistol broke ground with its interchangeable barrel system. The Encore rifle expanded that concept to handle everything from small-bore rimfires to dangerous-game cartridges. Inline muzzleloaders like the Omega and Encore 209×50 brought modern convenience to black powder hunting with threaded breech plugs and hotter ignition systems.

Even the company’s bolt-action rifles, like the Venture and Compass series, reflected a commitment to value without compromising accuracy. Across its product categories, T/C maintained a reputation for giving hunters adaptable tools that could meet multiple needs in one platform.

Why the Revival Matters

The disappearance of Thompson Center Arms from the market left a void for many shooters. Owners struggled to find parts, warranty service was discontinued, and the community of enthusiasts that had grown around the brand felt abandoned. Ritz’s return has already reignited enthusiasm, with loyalists eager to see both legacy products and new innovations roll off the Rochester line.

The revival also has broader significance: it represents a reaffirmation of American firearm manufacturing and the value of listening to the customer base. In an industry often dominated by corporate acquisitions and cost-cutting, Thompson Center’s comeback is a rare example of a brand returning to its roots, geographically, culturally, and philosophically.

A Call to the Community

Ritz is inviting hunters, shooters, and collectors to be part of the journey. Whether that means providing feedback, sharing stories of their T/C firearms, or simply keeping an eye on the upcoming releases, customer engagement is central to the plan. “The history of Thompson Center Arms is one of resilience, creativity, and excellence,” Ritz said. “We’re building on that legacy for today’s shooters and the generations to come.”

Looking Forward

By the end of 2026, consumers can expect a full slate of T/C products on the market: restored classics, thoughtfully designed new models, and a robust support system for existing firearms. Ritz’s aggressive but carefully staged rollout suggests that the company is not only back—it’s here to stay.

The renewed Thompson Center Arms is positioning itself as more than a nostalgia play. It’s aiming to reclaim its role as an innovator in modular firearm systems, a leader in muzzleloader technology, and a trusted name in American-made hunting rifles and handguns.

Thompson Center Arms acquires Green Mountain Rifle Barrels

Thompson Center Arms has acquired Green Mountain Rifle Barrel Company, a well-known barrel manufacturer based in Conway, New Hampshire. The announcement came in early August 2025, not long after Thompson/Center returned to being an independent, family-owned company under the leadership of Gregg Ritz. While now owned by Thompson/Center, Green Mountain will continue to operate as an independent entity, allowing it to serve both its existing customers and new demands from within the T/C product line.

Ritz described the acquisition as a pivotal move toward reclaiming craftsmanship and securing direct control over one of the most critical components in firearm manufacturing. Bringing barrel-making capabilities in-house strengthens Thompson/Center’s production capacity while preserving the reputation and heritage of Green Mountain. Both companies share a deep commitment to quality, innovation, and American manufacturing, with a strong New Hampshire presence anchoring their operations.

The acquisition means Thompson Center can more closely integrate Green Mountain’s precision barrel expertise into its own firearms. At the same time, Green Mountain will maintain its role as a trusted supplier to the broader firearms community. This step is part of Ritz’s broader vision for revitalizing Thompson Center by combining heritage craftsmanship with modern production capabilities, ensuring that the brand can deliver top-quality, American-made products for years to come.
