Or 9×22mm as its informal name) is a rimless handgun cartridge developed by Swiss-German firearms manufacturer SIG Sauer. in collaboration with a manufacturer of federal premium ammunition The cartridge is used by many law enforcement agencies.
.357 Glock Ammo
The .357 SIG uses automatic cases necked down 10mm in addition to specialized competition calibers such as the 9×25mm Dillon (1988), which chambers the 10mm AUTO down to the 9mm cartridge. Then the .357 SIG (1994) was the first modern commercial pistol caliber since the early 1960s that the Winchester Introduced a .257 caliber cartridge based on the now obsolete .256 Winchester Magnum (1960). Th Remington unsuccessfully introduced the .22 Remington Jet (1961), which downsized the .357 Magnum. only .22 and .221 Remington Fireball (1963), a shortened version of the .222 Remington.
Magnum Vs 10mm
Due to cost The effective .357 SIG ammunition costs about twice as much as the 9mm and about 50% more than the .40 S&W, so the .357 SIG never gained the same widespread acceptance as the .40 S&W.
This is because the cartridge was originally designed as a .357 (9.02mm) bullet, but this was quickly adapted to the .355 (9mm) bullet, according to the C.I.P. Internationale Permante Pour L'Epreuve Des Armes A Feu Portatives) 2008 revision, .357 SIG headspaces on case mouth (H2).
However, the cartridge and chamber drawings in the ANSI/SAAMI American National Standards clearly show the opening of the cartridge head at the mouth of the case.
According to the C.I.P. Judgment, the .357 SIG can handle piezo pressures up to 305 MPa (44, 236 psi). Proven at 130% of this maximum C.I.P. pressure to validate sales to consumers.

While using the neck-down 10mm case to accept 0.355-inch (9.0mm) bullets, the .357 SIG cartridge case is slightly longer than the .40 S&W, 0.23mm to 0.020-inch. (0.51mm) overall .. most S&W .40 revolvers can be converted to .357 SIG by changing the barrel. But sometimes the recoil spring also needs to be replaced. Handguns with super-strong recoil springs can accept whether or not the cartridge is barreled. The magazine will switch freely between the two cartridges in most revolvers. .357 SIG barrel kits have made this cartridge popular among handgun owners.
The table below lists typical performance parameters for many .357 SIG loads. Bullet weights range from 115 to 150 grains (7.5 to 9.7 grams), load weights from 488 ft-lbs (662 J) to 583 ft-lbs (790 J). and offers penetration depths ranging from 9 in. (230 mm) to over 16.5 in. (420 mm) for a variety of applications and risk assessments. Note: Underwood now also offers a standard pressure of 65 gr. .357 SIG Xtreme Defder (XD) with a muzzle velocity of 2100 fps, a muzzle range of 636 foot pounds and a penetration depth of 17.5 inches.
For handgun ammunition, the .357 SIG has an unusually flat trajectory. However, it is not as effective as .357 Magnum with bullets heavier than 125 grains (8.1 g). Ridge
Virginia State Police reported that the attack dogs were stopped dead in their tracks by a single bullet. Whereas the earlier 9mm 147 rounds required multiple rounds to incapacitate the animal.
Things To Know About .357 Sig
Hydrostatic shock theory asserts that the impulse contained in the .357 SIG is sufficient for delivering a hydrostatic shock to a well-designed ammunition.
The “Correct Powder” reloading guide claims to be “without a doubt the most loaded handgun barrel we have ever used.”
The goal of the .357 SIG program is to provide the same level of performance as the highly efficient 125-grain (8.1 g) .357 Magnum load.
Measurements of a standard factory .357 SIG shell loaded with 125-grain (8.1 g) bullets show a muzzle velocity of approximately 1,450 feet per second (440 m/s) from a 4-inch (102 mm) barrel, which is by Basically the same, with .357 Magnum bullet weight and barrel lgth the same.

These measurements were performed with a Thompson Seeter 1842 assault rifle, a single-shot pistol/rifle. Prevent different lgth caliber definitions between semi-automatic handguns and revolvers in order to give the revolver a muzzle velocity advantage.
According to simple physics The shrinkage is directly proportional to According to the "muzzle velocity × bullet mass" (due to preserving momentum) recoil of the .357 SIG is equal to or slightly less than that of the .40 S&W, and even less. More than a full power 10mm Autoload or the original .357 Magnum.
This simple method of recoil is incomplete because bullet properties alone do not determine the feel of recoil. But also the explosion of bullet-like gases coming out of the barrel after the bullet has left the muzzle.
A more precise aspect of recoil is proportional to ejection mass × ejection velocity.

To compare the energy levels of advanced self-defense ammunition. The muzzle has 584 ft⋅lbf (792 J) of 125-grain (8.1 g) energy at 1,450 ft⋅lbf (440 m/s). grain (10.0 g) 1,175 feet per second (358 m/s) Speer GoldDot .40 S&W load or 400 ft⋅lbf (540 J) produced by 180 grain (12 g) 985 feet per second (300 m/s) second) Speer GoldDot .40 S&W load.
In 1994, Sig introduced the P229 pistol, the first production pistol chambered in .357 SIG and specifically designed to handle the higher pressures of that round.
The ability to carry more ammunition per magazine (9mm vs. .357 SIG) in lighter guns is one of the reasons for the change.
That change was suspended after the A-2014 class recruits, the first cohort training. With S&W M&P polymer 9mm pistols, there were a number of issues with those weapons.

The newer version of the SIG Sauer P229 in .357 SIG is used by agts and officers of the following national and state law enforcement (LEOs): Wait a minute, the Glock 20 chambered in 10mm Auto is not. Or what does the .357 SIG have to do with the Glock 20? I'm glad you asked! The Glock 20 is awesome. But you can have more fun with the "G20" by adding inexpensive magazines for various cartridges. With my Glock 20, I can fire 10mm Auto, 40 S&W and .357 SIG by simply swapping out the barrel. No other parts or modifications required! Moreover These tanks only cost $100 (for the Lone Wolf variety I'm using), so it doesn't take a lot of money to "extend the range of your Glock 20." I wrote about my experience with Lone Wolf. 40 S&W dropped in the caliber. Now it's time to use the .357 SIG caliber!
My journey of loading and firing the .357 SIG was familiar: excited, prepared, then waited to explore this new cart. while this project is running I saw an email in the discussion group: 2000 single-shot SIG .357 brass: Clean and headstamp intact. This is exactly what I was looking for and was the "nerd" needed to keep this project going. Soon I'll be shooting a .357 SIG for the first time: with my own hands.
Above you can see my Glock 20SF with a factory 10mm Auto caliber, a Lone Wolf 20357N .357 SIG caliber-converted (front, left) and a Lone Wolf 2040N 40 S&W caliber-converted (front, right). Shoots that fit in a Glock 20 holster, but fires three different cartridges. This is a great setup!
The .357 Sig cartridge was designed and developed by SIG SAUER with the motive to replicate the 357 Magnum in a compact cartridge that easily adapts to most semi-automatic pistols. Starting with the 40 S&W* cartridge (more or less, see notes below), the mouth of the case necks down from the standard 40 caliber (0.400″) to accept 9mm (0.355″) rounds. It is similar to many "wildcat" rifle cartridges: neck down the case to accept a smaller diameter bullet that flies faster than the one from the modified parent cartridge. Sounds interesting right? I guess I'm obsessed with Naturally "abnormal," as you can imagine. I was excited to shoot and reload the new .357 SIG: It was definitely something different! I wanted to try using .400 Corbon ammunition, which is essentially a .45 ACP (which uses .451″ bullets) neck down to accept 40 caliber (.400″) bullets. "Cult following"

*Note that you can't make a .357 SIG from 40 S&W brass because you'll "miss it" - the 40 S&W case isn't long enough to make a .357 SIG case. Now I know what you're thinking.
