The .357 SIG is a 10mm auto body down the neck. In addition to specialized competition cartridges such as the 9mm 25mm Dillon (1988), the .357 SIG (1994), the 10mm Auto was the first modern bolt-action commercial rifle cartridge from Winchester to adopt the 9mm bullet. Introduced the .256 Winchester Magnum (1960), a .257 caliber round based on the now obsolete .357 Magnum.

Because of its performance, the .357 SIG practice bullet costs about 9mm and about 50% that of the .40 S&W, the .357 SIG was never as widely adopted as the .40 S&W.
This is due to the fact that the cartridge was originally designed for the .357 (9.02mm) round, but was quickly adapted to the .355 (9mm) bullet. Official C.I.P. .

Although based on a 10 mm neck to accept a 0.355-inch (9.0 mm) bullet, the .357 SIG cartridge case is 0.009 (0.23 mm) to 0.020 (0.51 mm) from the .40 S&W. is slightly longer than . Most .40 S&W pistols can be converted to .357 SIG by changing the barrel, but sometimes the recoil spring must also be changed. Pistols with particularly strong ejection springs can accept cartridges with a barrel change. Magazines are freely interchangeable between the two cartridges in most pistols. .357 SIG barrel sets have made this cartridge popular among gun owners.
The table below shows general performance parameters for most .357 SIG loads. A pill weight of 115 to 150 grams (7.5 to 9.7 g) is recommended. Loads are available from 488 ft-lbs (662 J) to 583 ft-lbs (790 J), from 9 inches (230 mm) to 16.5 inches (420 mm) and are available for a variety of applications and risk ratings. . Note: Underwood now standard pressures the 65 gr.357 SIG Xtreme Defder (XD) with a round velocity of 2100 fps and a muzzle velocity of 636 feet. and 17.5 inches deep.
For a rifled round, the .357 SIG has an unusually smooth trajectory, extending its effective range. However, with a heavier 125-grain (8.1 gr) bullet, it is not enough to match the performance of the .357 Magnum. Compensating for this common disadvantage is that semi-automatic pistols hold significantly more ammunition than revolvers.
Virginia State Police reported that the attack dogs were killed by a single shot in their tracks, while the previous 147-grain 9mm round would have required multiple rounds to incapacitate the animals.

Aspects of hydrostatic shock theory suggest that the recoil found in the .357 SIG is sufficient to produce hydrostatic shock with well-designed bullets.
The "Precise Powder" loading manual claims that it is "undoubtedly the most ballistically accurate cartridge we have worked with."
The goal of the .357 SIG project was to deliver the same level of performance as the 125 grain (8.1 g) .357 Magnum load.
Standard factory dimensions. Loaded with a 125-grain (8.1 g) bullet, the SIG cartridge exhibited a velocity of 1,450 feet per second (440 m/s) from a nearly 4-inch (102 mm) barrel. Belt weight and barrel length same as .357 Magnum.

These measurements were made with the Thompson Setter Core 1842 breaker action, single shot pistols/rifles, semi-automatic pistols and revolvers, which encouraged different definitions of barrel lgth that prioritized spin speed.
In simple physics terms, being directly proportional to "bullet speed × bullet mass" (due to recoil), the damage of the .357 SIG is equal to or slightly less than the .40 S&W, and at full power. Smaller 10mm auto or original .357 magnum,
This simple approach to recoil is flawed because it is not just the bullet's characteristics that determine the perceived damage, but the rocket-like explosion of propellant gases that exit the barrel after the bullet is fired.
A more accurate view of emission is proportional to the total mass of the object and the velocity of the object.

Compared to premium self-defense ammunition, the .357 SIG load has a larger 155 grains (10.0 g) than the 475 ft⋅lbf (644 J) at 175 ft/s (358 m/s) of the Spear Gold Dot .40 S&W. load or 40 S&W load. ft⋅lbf (540 J) in 180 grains (12 g) at 985 ft/s (300 m/s) Spear Gold Dot .40 S&W load.

The new SIG Sauer P229 .357 SIG has been approved for use by the following national and state law enforcement agency (LEO) officers and personnel: as two high performance medium rifle calibers, the .357 SIG and the .357 Magnums are a must. should be compared. Introduced in 1935, the .357 Magnum was designed as a long-range hunting revolver for small and medium game. It has evolved into a large stage for defense and law enforcement that can penetrate vehicle bodies and other light obstacles.
The .357 SIG was introduced in 1994 as a round with the same power as the .357 Magnum and chambered in 9mm and .40 S&W semi-automatic pistols. The advantage of the .357 SIG is that it can be loaded in a pistol with detachable magazines, giving shooters a powerful firepower.

The name ".357 SIG" indicates that the semi-automatic round is as powerful as a revolver, although the .357 SIG uses a 0.355-inch bullet like the 9mm. But is it? The published data is from a 4-inch barrel for the .357 SIG and .357 Magnum, as that is the standard barrel length as defined by SAAMI. But there is a difference.

The 4-inch test barrel is "windy". This is the distance between the chamber and the barrel, just like a revolver has the distance between the cylinder and the barrel. So the velocities you get from the test barrel should be the same from the original revolver. A 4-inch test barrel for a semi-automatic cartridge is the same bore as a real semi-automatic pistol, so the velocity of the test barrel should be the same as that of a standard pistol.
It shows the S&W Performance Center Model 686 with a 4-inch barrel used to test several .357 Magnum bullets. Some bullets were tested in the 4-inch S&W Model 65 submachine gun.
Here, we focus on the published ballistics for the 125-grain bullet, since that is the bullet weight that both cartridges share. Ballistics issued for Federal, Remington, Speer and Winchester 4 inch barrels. The exception is one bar (of three bars) offered by Speer, which runs at 1,325 f.p.m. In fact, the same spare load is the only one that doesn't produce full power, and even that load is only 25 f.p.p. Slower than others. SIG Sauer .357 SIG bullets at 1,356 f.p.m. It shows velocity but not barrel length.
