I would have never believed this. I always figured the pressure would spike from pushing the mass of the water in the barrel out with the bullet, causing a kaboom. Looks like I'm wrong if this video is authentic.

Mythbusters did a thing about shooting underwater once. It's not recommended to shoot a shotgun underwater. About the only way you would be injured, according the Mythbusters testing, was if you were shot point blank. Been awhile since I've seen it, so I might be off a little.

I saw on TV one time of a weapon which divers of some kind used to protect them from man eating sharks. It was a tube, about 24" long and contained a 12 gauge shell, looked like it fired simply by jamming it againt the head of the shark. Showed this in action, took care of the shark.

Works very effectively against any marine threat!

The shotshell is in the effective end also, not near the hand.

Mythbusters shot into the water, I don't recall them shooting under water unless that was another episode.

As much as I enjoy Mythbusters, the tests they do are hardly comprehensive.

The truth is, shooting a gun underwater, you have lots of variables. Is the barrel flooded or clear? Rifle or pistol? Shotgun? Ammo selected? Auto or revolver? And in any event even if the gun can survive, do you want your ears to be 30 inches from a firearm discharge underwater? Will the action also cycle?

I have seen kits to plug up the space under the dust on a G-17 to fire underwater, I'm not going to volunteer mine to see if it really works.

Years ago I shot my G17 under water. My head was above water. I stuck my arm and pistol into a creek a fired off a round. Worked fine. I only fired one round. Also, I held the gun with my left (opposite) hand--just in case. It was rather foolish of me to test my gun like I did, as I was backpacking at the time and was miles from the car. If something had gone wrong I'd have been in a tight spot.

why would anyone want to shoot underwater? and in what situation would a normal everyday person ever be in a situation to do so? Seems kinda pointless to me!:neener:

I suppose you can catch a fish that way. :D

Like shooting fish in a barrel maybe? :)

HK makes some VERY interesting under water weapons; specifically designed for under water use.

[jerkyman45]

The Soviets made an under water rifle and quad-barrel pistol for use under water. It was a standard 7.62 x 39 mm round that held a drag stabilized dart about 4 inches long. It was said to be effective to about 15-25 yards under water, and 100 yard in air. The dart was about 3 inches long. I'm not sure if they still make them, but they are nifty guns. The magazine on the rifle is goofy looking, with the top half being about 6 inches long and the bottom half being about 4 inches long.

Wikipedia has a pretty decent article on it: http://en.wikipedia.org/wiki/APS_Underwater_Assault_Rifle

Yeah I think they had one show where they were firing pistols off in a tub of water. None of the pistiols blew up, but I think only the .357 mag had any penetration at all. And that was a board about 3 inches in front of it.

I've never scuba dived but i think it would be awesome to pack a Glock 17 with you. I wonder what that would do to a shark?

I bought a video at a gun show a few months ago for $5, that was about an hour's worth of this guy out in California shooting various handguns in his pool. They had a couple camera angles, and a decent underwater setup, but he was foolishly using nothing but hollowpoints. Net result was that they functioned, and some of them functioned very well, but the bullet just didn't have much energy after a few feet. I still suspect FMJ would have been much more effective.

One of teh pro writers did this test, as well as firing full of ice, mud, crud, etc. Usually firing under water will fail to eject, and will frequently send the cartridge right back in but backwards.

IF you listened to them, Mythbusters actually were comprehensive, and correct. The gun has to be under water with the barrel FLOODED. KB's come from pressure spikes, such as a non flooded barrel and the compression of air in the barrel added to the current powder pressure. Their shotgun did go pop however.

[.38 Special]

Mythbusters used several handguns (don't remember the models), an M1 Garand, and a shotgun.

Nothing was effective against a target more than a few feet away, IIRC, and the shotgun blew up.

I used to freedive competitively and spearfish recreationally. It wasn't horribly uncommon to find spearfishermen carrying a pistol, almost always a Glock. Talked to a few guys who claimed it was a fairly effective weapon underwater if the muzzle was up against the target.

And yes, bangsticks are tremendously effective. For a while there was some video floating around of somebody using one against a middling (+/- 10 foot) white shark. The shot entered just ahead of the gill area and cut the fish nearly in half.

[the naked prophet]

Steve Zissou and his divers all carried Glocks. But all the interns had to share one :rolleyes:

I've wondered sometimes if The Life Aquatic didn't do that to make a little fun of the "tactical" spearfishing contingent.:p

[mfree]

My best guess about the shotgun was that the petals on the plastic cup probably caught fast against the choke since water's so much thicker than air (it's all fluid dynamics regardless) and caused the overpressure.

I've never understood the fixation of shooting a firearm underwater :confused: Diff't strokes for diff't folks :scrutiny:
