Does it go off? Explode? Does it matter whether it's gas operated?

Well, let's see...

Ready?

The world will end.

It depends, if it is a handgun, it probably won't hurt it.  It may go bang, it may not.  It may fire, but not eject.  It may fire, eject, and then not feed.  Or it may just go whump, whump, whump for the whole mag.  My PA63 went through a mag underwater with no problems.

Better not try it on a rifle.  Especially a gas operated one.

All in all, not really a suggested activity.

You'll Shoot your eye out...ah shit, I thought this was the Christmas Story thread. Nevermind.

The sonic boom will make you float up to the top of the water like fish do when you set off explosives in the water.  

I guess it depends if you hit it.

2 words: Black Hole

What is that, and where/how was it taken?

In the movie lethal weapon 4 Mel Gibson shot some kung fu master with a AK while underwater, it worked and the bad guy died.

It was on TV so it has to be true.

Depends on the gun.  Glock 17 can be fired under water. Glock even offers a special set of fluted firing pin cups, so the striker assembly will properly function.  Of course you want to use FMJ ammo so the resistance from the water doesnt causee the JHP to start to expand in the brl.

My manual for my HS2000 said it would fire up to 1 meter under water.... (shrug)

Make damn sure your ears are above water or start taking sign language classes now.

**** from a article*******
During the 60's and 70's when I was a diving fanatic, I made
about half dozen 12 gage powerheads for killing big fish.  Even
made one in .357 which still resides in my desk.  All were of
slightly different designs but all worked very well.  All were
"fire on impact" and they had the effect of a shotgun barrel
pressed up against the target - never lost a fish.  

In those days one diver, an ex-frogman, was renown for his taking
of great whites that were longer than boat from which he dived.  
His picture, taken at the instant of powerhead impact on a great
white's head was a cover of Life Magazine.  The shark's head was
about the size of the diver's body and the gaseous discharge
could be seen emerging from the bottom of the shark's head.  
After that I had no doubts about the powerhead's ability to take
500 pound jewfish.

I have fired boxes of 12 guage shotgun shells underwater in
powerheads of my own design.  This is also true of .357 magnums
in experimental powerheads.[red] The effect is a very muffled whump
that could in no way impair anyone's hearing.[/red]  This is true even
when shooting into a small cave where the sound was reflected
directly back at me.  In that case sometimes my mask was pushed
back against my face by the shock wave, but it was in no way
uncomfortable.  It's a great way to kill a grouper weighing 50 to
several hundred pounds if one is a meat hunter as I was during
college years.  

I have stunned grouper in small caves by shooting against the
cave wall next to the fish when it was too cramped to hit the
fish directly.  Usually the fish recovered in 2-3 minutes or so
but that was long enough to get him into the boat if I didn't
dally.  

Forty to fifty pound grouper were common in the Boca Raton,
Flodida area in 1964-67 and one fed us for a week.  Really large
ones were around on occasion but they would not fit into our
refrigerator freezer and had more worms than the smaller ones.
