B&T suggested using the Welrod design but adapting it for 9 mm which the customer agreed to.
Initially only 30 were made, 25 for the customer and 5 for hobby use by B&T employees, but production and sales were expanded when it was realized that there was a market for such a pistol.
[5] Beginning in 2021,[6] Brügger & Thomet began importing a version of the pistol to the United States as the Station SIX-9.
To comply with American handgun regulations, the barrel length was increased and the grip was lengthened.
[8] A second .45 ACP variant called the Station SIX-45 with a further lengthened grip and feeding from M1911 magazines was also announced.
