The .357 SIG is a rimless bottlenecked pistol cartridge developed in 1994 by SIG Sauer. While it is based on a .40 S&W case necked down to accept 0.355-inch (9.0 mm) bullets, the .357 SIG brass is slightly longer (0.009-inch (0.23 mm) to 0.020-inch (0.51 mm))
.357 refers to the cartridge having similar ballistics to 125 grain .357 Magnum revolver round. SIG refers to SIG Sauer, the company which developed the cartridge.
The cartridge is not proprietary. Other manufacturers, such as Glock, also offer pistols in this caliber.
Most .40 S&W pistols can be converted to .357 SIG by replacing the barrel, but sometimes the recoil spring must be changed as well. Pistols with especially strong recoil springs can accept either cartridge with a barrel change. Magazines will freely interchange between the two cartridges in most pistols. .357 SIG barrel kits have allowed this cartridge to gain in popularity among handgun owners.
However, the .357 SIG is loaded to higher pressures than the .40 S&W and may not be suitable for use in all .40 S&W-chambered pistols due to the increase in bolt thrust.
C.I.P. and the SAAMI pressure limits for .40 S&W are 225 MPa and 35,000 psi.
According to the C.I.P. guidelines the .357 SIG case can handle up to 305 MPa (44,236 psi) piezo pressure. In C.I.P. regulated countries every pistol cartridge combo has to be proofed at 130% of this maximum C.I.P. pressure to certify for sale to consumers.
The SAAMI pressure limit for the .357 SIG is set at 275.80 MPa (40,000 psi), piezo pressure.

How many different types of ammo are there for a 357 I got 357 mag and 357 sig and neither fits your 357 colt python?
a 357 cal. revolver cartridge WILL fit a colt 357 python. Also, a 38 special will fit a 357 cal. python. The 357 sig cartridge will NOT fit a 357 colt python................ The 357 sig cartridge ONLY fits the sig model pistol For clarity.....the sig 357 is a pistol. But, the 357 python is a revolver................

Does anyone make a 357 Sig Barrel for a Smith and Wesson Model 4006?
I am trying to make a deal with a coworker who says his 4006 came as a dual caliber gun .40 cal and .357 mag. I know the gun cannot be .357 mag so it must be a .357 sig. I have not yet seen the .357 barrel. I do know that Bar-Sto makes a .357 sig barrel as I just read the article on reloading .357 sig. Search google for 4006*.357 sig.
Can a sig sauer sp 2022 40 cal be converted to a 357 caliber?
The answer is yes....and no. By performing a barrel swap to the 357 sig barrel the gun is capable of shooting the 357 sig round. However, the 357 sig has a much higher barrel pressure (5000-10000 more psi). While the gun can shoot the 357 sig round simply by changing the barrel, this will cause more wear than is normal and can possible damage the slide. The safe bet is to buy a slide and barrel meant for the 357 sig round.
Can you fire a 357 round from a sig p226 40 cal pistol?
Yes, you can fire a .357 Sig round (not a .357 Magnum) in it, but you must first change out the .40 barrel for the .357 barrel.
