History of 357 Sig Ammo
Introduced in 1994 by SIG SAUER and Federal Premium Ammunitions, the .357 SIG cartridge features a rimless, bottlenecked case designed to mimic the velocity and stopping power of the .357 Magnum while being fired from a semi-automatic pistol. Initially, the bullet size was .357 inch but was quickly reduced to .355 inch for ease of use. As the first bottleneck commercial handgun cartridge since the early 1960s, the .357 SIG typically has a 125 grain bullet, matching the average weight of a .357 Magnum bullet, and achieves an average velocity of 1,350 feet per second with a muzzle energy of over 500 foot-pound force. Contrary to some sources, the .357 SIG casing, slightly longer and thicker than the .40 S&W, is more akin to a necked-down 10mm case.
How does .357 SIG Compare to Other Calibers?
| Specification | .357 SIG | .40 S&W | .357 Magnum | 9mm |
|---|---|---|---|---|
| Bullet Diameter | .355 inch | .40 inch | .357 inch | .355 inch |
| Velocity | 1,350 fps | 1,130 fps | 1,450 fps | 1,180 fps |
| Muzzle Energy | 506 ft·lbs | 468 ft·lbs | 583 ft·lbs | 355 ft·lbs |
| Max Pressure (SAAMI) | 40,000 psi | 35,000 psi | 35,000 psi | 35,000 psi |
| Performance | High speed, good penetration | Decent speed, good damage | High speed, high impact | Low recoil, high capacity |
357 SIG Ballistics: Chart of Average 357 SIG Ballistics
In its standard form, the .357 SIG features a bullet with a .355-inch diameter that fits into a .381-inch bottleneck. The cartridge base diameter measures .424 inch, while the case itself is .864 inch in length. With the bullet sitting in the bottleneck casing, the full length of the .357 SIG comes in at 1.140 inches.
When it comes to ballistics, the .357 SIG shows some significant numbers and, with a 125 gr bullet, can easily compete with the .357 Magnum. Although it’s a smaller casing, it’s still a powerhouse and great option for a self-defense round.
Note: This information comes from the manufacturer and is for informational purposes only. The actual ballistics obtained with your firearm can vary considerably from the advertised ballistics. Also, ballistics can vary from lot to lot with the same brand and type load.

Rob said:
The 357 SIG ammo was great it handled and fired as expected every time. No mishaps and all rounds mostly hit the target every time unless I interfered... LOL Have recommend this product and your delivery to other friends...

Ammo arrived promptly and performed as expected.

Sam said:
I feel that due to the few numbers per capita of the .357 Sig guns, the demand isn't so high which makes even the practice loads high in comparison to o ther calibers. This ammo shoots very well and is close to my carry load (Gold Dot) in felt recoil. Over all very good and I will buy more later. Cheers, Sam

Coreyl said:
Got this ammo for a great price in bulk. It performed great also. The store is a lot more even on sale . So this ammo is a great buy for us people that have the somewhat oddball calibers. Along with fast shipping it’s a win win situation

Greg said:
I've used Remington ammo previously and thought I'd give it a try in 357 Sig for my new Sig P320 Compact. I've only shot about 200 rounds of the 500 rounds I ordered so far, but all of them have been issue-free. For the price Ammo.com was asking you can't ask for more than that. Good stuff and I would order again without hesitation.

ammo performed well no miss feeds or failures to go boom. would hope in the future that the packing would include a box with a tray just a thought. not the hottest load ive ever shot but all in all a good target load.

Carlos said:
Well shooting ammo, no FTE or FTF. Solid plastic bag, some brass casing mixed in with nickel case, but did not affect quality. As soon as back in stock, I will be buying more. Thanks

I loved this ammo. Very accurate.

Shot ammo in a Glock 27 Gen 4 with a Storm Lake 357 sig barrel with very little problem. Ammo jammed a couple of times, but I don't think the ammo was the problem. I will buy more Prvi Partizan ( PPU) ammo when possible in .40 cal, 9mm, and 357 sig. Great stuff.

One would be hard pressed to find a better price, better quality or better performing ammo that is used for practice and 'plinking'. I went through all the ammo on this order and was very satisfied with my purchase. I had no misfires, no jamming or excessive dirt build up. I will certainly continue to buy from Ammo.com and Ammo.com will be the first ammunition supplier I look to for quality and value in my purchases. Thank you Ammo.com for your commitment to our 2nd Amendment.

I believe this is the ultimate .357 sig ammo. Accurate and effective.

Chris said:
The round has incredible velocity and stopping power, and it is very snappy in anything but a Glock 31 gen 4. Accuracy is very good. Great round if price is not a concern.

Not the cheapest ammo out there but does the job 100% of the time for me. I figure if the times comes for lethal force I only want ammo I can count on.
