Description:

The 357 SIG cartridge was developed by SIGARMS in partnership with Federal Cartridge.The cartridge uses a bottlenecked .40 S&W casing crimped to a 9mm bullet. This is why the 357 SIG is not written as '.357', as it is not truly a .357 caliber bullet, but is instead a standard 9mm bullet (.3550 in). The 357 SIG design is an attempt to create a cartridge with stopping power that would approach the larger .357 Magnum revolver round, but in a smaller package that can fit comfortably in the grip of a semi-automatic weapon. Despite the manufacturer's claims, it is not quite as powerful as an actual .357 Magnum, but it exceeds the power of a .40 S&W cartridge.
