357 SIG Ammo

.357 Sig ammo was jointly designed by Swiss firearms manufacturer Sig Sauer and the Federal Cartridge Corporation. The intent of the designers was a cartridge comparable to the .357 Magnum and capable of firing from semi-automatic handguns.

The .357 Sig round is derived from the case of the .40 S&W, necked-down and slightly elongated. This bottlenecked case design makes .357 Sig ammunition exceptionally reliable when feeding in semi-automatic firearms.

While the original ammunition utilized a .357 diameter bullet, the design was quickly revised to utilize .355 caliber (9mm) bullets which are typically shorter than standard 9mm bullets due to the length of the case neck. Most bullets used in .357 Sig are truncated cones, whether FMJ or hollow-point.

Common weights for .357 Sig projectiles are 115-grain, 125-grain and 147-grain. The heavier bullets are capable of exceeding 1200 feet per second muzzle velocity out of common barrel lengths, while the heavier bullets can reach over 1600 feet per second. Muzzle energy for the various loadings ranges from just below 500 foot-lbs to over 600 foot-lbs.

Adopted by numerous law enforcement agencies, including the Texas Highway Patrol, US Secret Service and Federal Air Marshals, .357 Sig ammo is ideally suited to duty and personal defense. Its combination of weight and velocity marks it as a hard-hitting caliber, while its notable case dimensions make it one of the most reliable pistol calibers in existence.
