357 Sig Ammo

A bottleneck cartridge developed by SIG and Federal, the .357 SIG is designed to bring the legendary ballistics of the .357 Magnum to semi-automatic handguns.

Like its revolver cousin, the .357 SIG works best for self-defense when firing a relatively light 125 or 147 grain bullet at a high muzzle velocity of 1200-1400 feet per second. This delivers strong expansion and penetration, though shooters are well advised to train well for the kick!

Handguns available in .357 SIG include the SIG P229, Glock 31/32/33, and Springfield XD. The list of agencies using the .357 SIG is somewhat longer and includes the US Secret Service as well as the state police forces or highway patrols of Delaware, Montana, Virginia, and Mississippi. You'll find loads produced by Remington, Federal, Winchester and more for sale here at Widener's.
