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.

    Match popular defensive ballistic performance choices at your next match or practice session with these .357 SIG rounds from Fiocchi. These rounds are constructed using non-corrosive Boxer primers fitted into reloadable brass casings which are topped with full metal jacket - truncated cone (FMJ-TC) projectiles. FMJ-TC bullets have a sloping conical ogive and a flat top surface (similar to a semi-wadcutter) which leaves nice clean holes in paper and cardboard targets for match scoring. The FMJ-TC shape also reflects a common profile for many .357 SIG hollow-point rounds so that your practice ammo can proof cycling and feeding for your carry/duty ammo.

    These bullets weigh in at 124 grains which is light for the caliber and produces an relatively high muzzle velocity of 1,350 feet-per-second. The light weight provides a lighter recoil for the high pressure round while also mirroring the firing and flight characteristics of many .357 SIG defensive cartridges which use 124 grain Hornady XTP projectiles.

    Fiocchi is one of Italy's oldest and largest ammunition manufacturers and is located in Lecco at the heart of a close-knit firearms industry community. With nearly 140 years of experience behind them, Fiocchi is one the world leaders in ammo innovation with products aimed to pleased hunters, competitive shooters, law enforcement agencies, and private citizens.

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.

    These cartridges are loaded in Oxford, Mississippi and use non-corrosive Boxer primers and reloadable brass cases.

    The .357 SIG cartridge, as the name suggests, was developed by SIG Sauer. The first pistol chambered for the .357 SIG was the P229, which is used by a number of US law enforcement agencies.

    Each .357 SIG cartridge in this 50-round box fires a 125 grain projectile at a muzzle velocity of 1,350 feet per second, producing the flat trajectories, strong terminal ballistics, and stout recoil associated with this caliber.

    This ammunition is loaded in Lewiston, Idaho using non-corrosive primers from Speer's sister company, CCI. For additional durability, these cartridges use nickel-plated brass cases that can withstand long periods of carry.

    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!
