Finally, Found a Good Use For Glocks - Shark Guns!

I was talking to a long time dive buddy of mine who had just come back from the Sea of Cortez. If anybody else told me this ... I wouldn't have believed it!

There is/always has been a 'hammerhead problem' around the Seven Sisters (islands) - as the sun descends close to the horizon the HHs begin coming up. A few of the Mexican divers and a friend of his carry Glocks on the weight belts! ... I'd like to wear one off La Jolla Shores on my next club dive ... can you imagine the looks you'd get!?

The Glock WILL fire underwater.

There is a special firing pin retainer for that use. They don't use Hydra Shock ammo underwater - or gun will blow up. The bullet will only go a short distance - they are using their G17's for shark defense at contact distances.

... well, I'm getting close to, 'Have heard of everything, now!'

Interesting ... but ...

I read the entire piece but I'm a little suspicious.

We used to make/use .12GA bang sticks on three foot handles. The water muffles the sound - it doesn't amplify it. If it did, I'd be stone deaf ... and would have been for the past 45 years - my hearing is still perfect!

looks like the glock worked just fine, and it cycled just fine. thats pretty cool footage!

Were you under the water when firing? If not, then you are confused as to what the article is saying...If your ears are submerged with the firing weapon, THEN it is louder...not if you are above the water in the air. Sound travels better through water than air...

Very TRUE!

The bang-sticks you're talking about are meant to be a contact weapon. The force of the concussion from the shotgun shell going off is directed into the body of the shark (another reason it is so devastating aside from the pellets). It seems muffled to you because it's all going into the shark.

Now, if you were to fire off a 12ga shell in open water..... I guarantee it wouldn't sound muffled. The sound from the shot going off is actually a shockwave, which after being amplified underwater is a concussion wave. It has physical force behind it and can damage more than just your hearing. There are explosive blasting techniques which utilize this principle to sympathetically detonate multiple charges spread over a distance.

After dealing with explosives for "a few years" in the Marines, the cumulative effects of concussion & blast injuries are something I'm aware of.

Your entire body sustains damage from an underwater concussion, not just your hearing. It's only because most people never think about what that concussion wave is doing to their brain, their lungs, their eyes, etc.

The water muffles the sound - it doesn't amplify it.

Denser materials conduct sound more efficnently than less dense materials.

solid > water > air

I hope you're wearing hearing protection.

haha i learned this when i was a little kid in a reallllly big college pool...

It's a very very simple test and its very very safe- provided you know how to swim

Take any water proof/resistant stop watch that can repeatedly go beep every second or so. Let it beep and walk away and see how far you can go before you can't hear it anymore.

Now, jump into the water with the stop watch and drop it. Submerge your head and swim underwater.. Now see how far you can go before you cant' hear the beeping. I guarantee that if there arent' tons of kids/adults splashing, you'll go quite far before that beep becomes inaudible.

Safe, easy and you dont need to blow out your ear drums to see that 'sound waves' travel quite nicely through water.

Yeah, I always used to try to talk underwater too, but that never worked. All I could do was make noises like a whale..

From what I remember from SCUBA a long time ago, sound travels 4 times faster in water than air. Fast enough that your ears (which are adapted for use in air) will have trouble determining where the sound came from.

Yeah this is true as well. Similar to to the post earlier with the stop watch, when I played highschool waterpolo someone showed us a cool trick also with a beeping watch. They would have us close our eyes and they would then submerge the watch somewhere in the pool without letting us know its location. We then had to try and swim around looking for it. Since our ears use the time difference it takes a sound to travel to our right ear vs. our left to dtermine the origin of a noise, the faster soundwaves underwater aren't what we're calibrated for, and we can't tell where the sound is coming from.

I thought it was illegal to take your gun to Mexico or in Mexican waters? I know of a friend that was in jail for 2 days just for having BULLETS for his bang stick while fishing in Cabo many years ago. Mexican rules are kinda crazy.
