About the Gun

One of the first successful polymer framed designs, Glock handguns are common sidearms among law enforcement agencies and military organizations around the world. Although a striker-fired pistol, the Glock employs a single-action (SA) trigger, meaning that the trigger does not cock the gun, but only releases the striker when pulled. Cocking of the striker is performed by the retracting slide. Glock pistols have no manual safeties. The trigger is the only operating element. All three internal pistol safeties are deactivated when the unique single-action trigger is pulled, and automatically activated when it is released. For more information on the Glock design, please refer to the Glock pistol animation in the Basics section.

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.
