okay-been watching too many mystery/detective movies lately.
You know the ones-somebody lands underwater for some reason holding a gun. Then rises to the surface and starts shooting. Is that possible? Will a wet gun fire?
Yes, though it can be damaging to the gun. There's a great deal of pressure inside the chamber and barrell when a gun goes off and objects or fluid can cause too much pressure or an uneven distribution of pressure. A gun can actually be shot underwater, technically. YOU SHOULD NEVER ATTEMPT TO DO THIS!
Yes, most cartridges, while not water proof, will not allow enough water to seep past the bullet or primer to deactivate the powder charge. Guns can therefore be fired under water, but your question was can they be fired after being in the water. Yes, no damage would result if all of the water had drained out of the barrel, but if it hasn't some damage may result, depending on the cartridge. Water in the barrel would act like anything else that caused an obstruction, usually there is damage, sometimes destruction of the firearm, but not always.
most military rifle ammo has laquer sealed primers & bullets, you could drop an AK47 in the water with a full magazine and pull it out a week later and it would most likely still fire all the cartridges
There is a specially available gasket which allows the GLOCKs to fire under water or immediatly after being submerged. They are not available to the general public.
Ask a Navy SEAL if a gun can shoot after being submerged...
those are usually specially designed to do that, or to drain faster after being submerged. SEALS get all the good stuff.
just because some firearms *might* be able to fire underwater doesn't mean it's a good idea, and it's been shown that firing a regular firearm underwater or even into water doesn't do a whole lot besides make a splash.
A gun may fire right after becoming wet. But if it isn't dried out properly, the inside of the barrel may rust making the gun not able to be fired safely (if it fires at all).

Rust will start on all parts of the firearm if it's regular steel, but there are a lot of guns made out of metals that resist rust, like stainless steel.
PAHippo, I'm sure you know that what you see in the movies does not always depict what actually happens in real life. If I were to be underwater with a firearm, I would definitely not fire it because it might damage the gun and you'll injure yourself in the process. Besides, the projectile (bullet) will be useless because it won't travel too far after firing it and it won't have any energy when it strikes the intended target. I don't think anyone else mentioned it, but there's also a chance, depending on various factors, the projectile will get stuck in the barrel, which will require a gunsmith to remove it. For various underwater purposes, there are other types of weapons that are available, like spear guns.
