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.
Yes.
Yes you can. The bore is the same size.
Your gun is a 357 and can shoot both 357 ammo and 38 special ammo. The nice thing about these guns is you can practice at the range with 38S bullets, which are much cheaper, and save the 357 ammo for home defense.
38 Special and .357 Magnum.
No. 38 Special only.
No. Ammo designated as .38 or .38 special is different than ammo designated as .380. .380 is designed for semi-auto handguns and .38 ammo is for revolvers.More to the point, the .38 Special has a longer case, and a larger diameter projectile. The .38 special bullet measures .357" diameter, the .380 measures .355" diameter. The .38 special is a 'rimmed' cartridge, and the .380 is 'rimless'. Luckily, .38 Special ammo will not fit in a .380 magazine, otherwise the results could be disastrous, possibly turning your .380 handgun into a hand grenade.
case length is the main criteria. If the 357 is loaded and placed in the 38 special it will extend beyond the cylinder. But the 38 special can be used in the 357 with no problems.
Yes, you can shoot 38 specials through a .357 magnum revolver.
Nope. 357 magnum cartridge is too long, and too powerful.
Yes. The 44 magnum can fire 44 special ammo in the same way a .357 magnum can use .38 Special.
.357 Magnum and .38 Special (to include +P and +P+ loadings).
Yes it can. I do not think you will exceed the .357 pressures with .38 +P.
