The .440 Cor-Bon is a large-caliber handgun cartridge, first produced by Cor-Bon in 1998. Although it looks similar to a .357 SIG, this cartridge was designed after being necked down from an existing cartridge, the .50 AE to accept a .44-caliber (.429 in) (10.89 mm) bullet. This is fairly typical in the wildcat cartridge industry.
