Is the taurus 357 magnum waterproof?

Answer 1

Well, most guns are waterproof in one sense of the word- they do not dissolve in water. Can it be FIRED underwater? Yes- but whether it can be SAFELY fired underwater is another matter. Guns that are fired underwater are subjected to pressures that they were not designed for, and the bullets go only a short distance. If a gun has been submerged under water, it should be drained, dried, and lubricated.
