no the magnum round is only for revolvers the correct round to use would be the .357 sig
No - they are very different cartridges.
No, you can only use .38 caliber rounds.
No. However, .38 Special ammo CAN be safely fired in a .357 Magnum firearm. Both cartridges use a bullet that is .357 in diameter- but the .357 magnum is longer, and more powerful.
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 357 SIG magazine will not fit in a 40 caliber Glock such as the model 22.
Yes, you can use .38 rounds in a .357.
.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.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
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.
This seems to be a persistent myth. The .40 S&W/.357 Sig magazines are not compatible with 9mm Glocks.
The .357 Magnum was the first gun to use the term magnum.
Police most often use the 9mm Glock 17 or the .40 S&W Glock 22. The glock 17 magazine holds 17 rounds (+1 in the chamber), while the Glock 22 holds 15(+1).
