The 2.34 mm Rimfire or 2.34 x 6 Swiss Mini Gun cartridge is a small rimfire cartridge produced by the Swiss company Swiss Mini Gun and is specifically designed for the C1ST revolver. Both the firearm and the cartridges are manufactured entirely in Switzerland and are available only by special order. The 0.128 g (1.97 grain) bullet has a velocity of approximately 120 m/s (400 ft/s), resulting in a kinetic energy of just under 1 joule.[1][2][3][4]

Just like the revolver for which it was designed, the cartridges are produced only upon request, costing around $10 per cartridge, however, the weapon cannot be marketed in the United States because it does not meet the criteria for a sporting weapon under ATF Form 4590.[3]
