Yes, but, not recommended.
.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.

It CAN be, but would have it checked by a competent pistol smith first.
100-1000 USD
NO!!!!!!!!!!!!!!!!! DO NOT TRY THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
No, the 22 Mag will not fit.
it shoots 10 rounds per second and the mag has 30 rounds so you could use 3 seconds to shoot all the bullets from the mag
That would be 38cal. ammo
.357 Magnum and .38 Special (to include +P and +P+ loadings).
10-1000 USD depending on specifics
Desert eagle 357 mag.
