In 2012, a patent held by Strayer Tripp International on the two-piece 2011 receiver design expired. The design, a modernized 1911 with a separate grip module bolted to a serialized aluminum frame, had been locked up by STI's intellectual property for years. Its expiration opened the category to new manufacturers and set up the market into which Atlas Gunworks would enter. Adam Nilson, a USPSA competitor who had grown tired of 12- to 24-month wait times from existing 2011 builders, and Tod West, a machinist, decided to build the guns themselves rather than keep waiting.
Nilson brought a background in finance and small business; West brought years of tool-and-die work. Neither had built a production firearm before. Their early pistols were made with help from Allan Zitta, an IPSC World Champion and 30-year 1911 gunsmith living in Vermont at the time, who was willing to teach the pair his methods. What started as Nilson asking West for a few custom pistols became, within a few years, a full-time operation. Atlas Gunworks was established in Shelburne, Vermont, in 2014, on a simple premise: hand-fit competition pistols shouldn't take two years to deliver, and the shop building them should answer the phone.
The catalog grew from a handful of open-class race guns, among them the Chaos, into a broader range that also included defensive and duty-oriented models. Atlas builds its own magazines, slides, and small parts rather than outsourcing to the same suppliers other 2011 makers draw from, which is part of how it keeps lead times shorter than the segment's reputation suggests. Its current 9mm lineup, including the Athena, Erebus, Apollo, Artemis, EOS, Nyx, and Titan, uses a modular grip system the company calls the Alpha Grip, letting a shooter change panel size without sending the pistol back to the factory. Atlas has also paired with Agency Arms on a limited, hand-built collaboration called Project Alias, with each pistol assembled start to finish by a single gunsmith.
Atlas has no documented military or police contracts and does not present itself as a duty-gun supplier to agencies. Its reputation is built inside the competition circuit instead. Team Atlas shooters compete across USPSA, IDPA, and 3-Gun, and Nilson still shoots company guns at major matches, including the Dragon's Cup. Its pistols turn up regularly at Level II and national-level matches, and dealers tend to place the brand alongside Staccato and STI in the wider 2011 category, which has expanded sharply over the past decade.
For a collector, the appeal has less to do with rarity in the vintage sense than with scale: each gun is still largely hand-fit in a small Vermont shop rather than run down a high-volume line. Production is limited enough that popular configurations sell out, and Atlas does not offer pre-orders. Prices run from roughly $3,000 for entry configurations up to $6,500 or more for a fully optioned Erebus or a Titan RDS with a DLC finish. At SHOT Show 2026, the company showed its broadest catalog yet, spanning defensive, competition, and hybrid models, a reasonable marker of how far the shop has come from two friends solving their own wait-time problem.
