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.

    Excellent ammo

    I've used Speer Lawman for as long as I have been able to get it. I shoot it in a S&W M&P, Sig P320, Sig P226 X5 AllAround and Sig P229. 100% reliable, it actually meets the Sig357 performance spec, and is as accurate as I can shoot it.

    Federal Tactical LE is a great round for law enforcement and self defense. Anything coming from Federal will be high quality, due to their 94 years of experience, but these Tactical LE rounds are special, made specifically for law enforcement.

    If you are looking for a great self defense round, look no further than these HST, jacketed hollow point rounds. Federal's HST line of self/home defense ammo is purpose made to be in the top tier of reliable defensive ammunition. The HST bullet has 100 percent weight retention through most intermediate barriers and has a great track record of penetrating barriers without plugging. The 357 Sig has been proven by law enforcement as having great stopping power and damage, and with these jacketed hollow point bullets, they are even more so.

These .357 SIG cartridges fire a 125 grain full metal jacket bullet at a muzzle velocity of 1,350 feet per second, delivering the flat-shooting ballistics and stiff recoil typical of this caliber.

    Please take note: 357 SIG is different than 357 Mag ammunition, and it will not fire in 357 Mag firearms.

    Federal Personal Defense HST ammo may be marketed to the private sector, but it’s every bit as high quality as the old Minnesotan company’s police-grade ammo. While this cartridge’s 125 grain JHP does lack a bonded jacket, its mechanically locked jacket and core effectively deliver 100 percent weight retention or very close to it. The HST bullet even holds itself together if it has to pass through sheet metal!

    A bullet that stays intact is able to penetrate a threat to the optimal depth for takedown terminal performance. The HST bullet’s clog-resistant nose cavity also helps it to avoid over-penetration while simultaneously tracking a wide and devastating wound channel through surrounding soft tissue.

    This ammo’s Boxer-primed brass cases wear nickel plating. The thin layer of metal enhances lubricity to promote more reliable cycling in a semi-automatic, and it’s also less susceptible to corrosion than bare brass alone. The HST bullet’s own nose profile is also contoured to feed more reliably – a welcome advantage for a self-defense load!
