About the Gun

The Gen 4 series of Glock pistols were introduced in 2010. Like most new polymer framed pistols the Gen 4 series features interchangeable grip inserts. The Gen 4 series also incorporates a dual recoil spring assembly, a feature only in previous generations' compact models. Other features include a reversible magazine release, a Tenifer matte finish slide and new grip texture. Changes in the Gen 4 design are significant enough such that not all parts can be mixed and matched with previous Glock generations.

About the Cartridge

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.
