No. The 357 SIG magazine will not fit in a 40 caliber Glock such as the model 22.
This seems to be a persistent myth. The .40 S&W/.357 Sig magazines are not compatible with 9mm Glocks.
no the magnum round is only for revolvers the correct round to use would be the .357 sig
Most newer generation Glocks can shoot the .357sig in a .40S&W with a simple barrel change. You can use the same magazines. The same is true for shooting .40 in a .357 Sig. This is true with Sig Sauer guns as well. I have a Glock 23 (.40 S&W). I simple install the Glock 32 barrel (.357 Sig) which I purchased for $100. I can shoot .357 sig out of the same gun. The magazines (at least for Glock) for the .40 and .357 sig are interchangeable. You CANNOT safely shoot a .40 out of a .357 sig barrel or vice versa. A barrel swap is required. If you load a .357 Sig round into a barrel chambered in .40 S&W, it could fire, but it would probably cause damage to the gun and won't be accurate. .357 Sig has better "terminal performance" than the .40, but the .40 shells cost less which translates into more practice for the same $$$ with the .40, and better self defense with the .357.

No. Revolvers use the rimmed .357 Magnum cartridge. While there are automatics designed to fire this cartridge (Coonan and Desert Eagle, primarily), it's not the same as the cartridge you had in mind. If you saw a Glock marked '.357', that means it's chambered for the .357 Sig cartridge - not the .357 Magnum. While the .357 Magnum is essentially a lengthened .38 Special, the .357 Sig is an entirely different cartridge, consisting of a .40 S&W casing, necked down to fit a 9mm projectile. The cartridge name is a reflection of the attempts at the designer to come up with an automatic pistol cartridge which could duplicate the performance of the .357 Magnum.
No. The 9mm is not compatible with the .40 caliber frame/slide. On the other hand, you can put a .357 SIG barrel into a Glock 22 and use your .40 magazines.
Only in firearms chambered for it. SIG comes to mind, but, there are others.
No. 357 SIG and 357 Magnum are two very different cartridges. You can use .38 Special in a .357 magnum gun, but not 357 SIG Adding to the above, the compatibility of .38 Special and .357 Magnum applies only to revolvers. You cannot cycle .38 Special in a magazine fed .357 Magnum lever action or semi automatic.
.357 Sig and .357 Magnum are not even close. .357 Magnum is a rimmed, straight walled cartridge for use in revolvers. .357 Sig is a rimless, bottle necked cartridge used in semiautomatic pistols. They don't even use the same bullet diameter. Other than the name, there is almost no similarity. In other words, NO.
DO NOT ATTEMPT THIS!! Never fire ammuntion in a weapon that it is not chambered for.
Glock 17 and 19 They actually use Sig-Sauer P228's.
