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.

    Bulk up on high quality .357 SIG ammo with this 1000 round case from Fiocchi. Fiocchi's ammunition comes from Lecco, Italy where many shooting-related industries are clustered together. A close relationship with end users and weapon designers as well as almost 140 years of experience has kept Fiocchi at the peak of the industry with a slew of ammo lines for any shooting discipline.

    These .357 SIG cartridges are assembled using full metal jacket - truncated cone (FMJTC) projectiles which weigh in at 124 grains. 124 grains is light for the caliber and lends a lighter yet snappier recoil for the high pressure round as well as a high velocity of 1,350 feet-per-second. FMJTC bullets have a angled sloping wall leading to their flat tip which, in addition to the 124 weight, mirrors the profile of the popular Hornady .357 SIG XTP hollow-point. This allows you to practice with rounds that reflect both cycling and flight characteristics of some of the better defensive choices in the caliber. These rounds are also constructed using reloadable brass casings fitted with non-corrosive Boxer primers.
