Grains of what? Are you referring to powder, bullet weight, or something else?
Glock makes a couple of models that will fire the .357 Sig cartridge, and Sig makes a couple of models that will. Right off hand, I don't know of any others, although there may be some.
If the weapon is chambered in 357 Magnum, you can fire the round in it.

Depends entirely on which 357, and the condition of both guns. Some are worth more, some less.
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.
Long guns and hand guns.

They have been killed with everything from 22 LR on up. I would have a .357 at the minimum.
