Do you really need maritime spring cups for your Glock?

Will a Glock fire under water with factory spring cups?

Don't shoot the Sasquatch, it's illegal in several states ! Use your ice cream to entice the primates out of the pool before their long fur clogs the filters.

Your obviously have not been to Texas lately! ;)
 
IIRC - in past threads on underwater Glocks, it was stated that they were in common use for divers in Australia for shark defense.

There used to be zillions of underwater Glock threads.

Now someone will ask if you can shoot a Glock in space. Remember those?

:rolleyes:
 
I goofed on the vote, thought it was on the OP's title question...
then noticed it was "Will it work?", to which the answer is a Definite Yes, multiple times.

Ever been in the water with a hungry alligator?
You'll appreciate being able to dump an entire mag of 10mm into the 'gator ;)

IIRC, the Glock 17 9mm was designed to be able to shoot under water. Not the 10mm!. I would not install the marine cups on the 10mm and fire it under water. Now, if someone has fired successive shots underwater with a Glock 10mm, I'd like to see the youtube of that!:eek:
 
Does anyone know the effective range of say, a Glock 17 9mm under water? How close do you have to get to that gator's head to yield a kill shot? From tests posted on youtube with water jugs you're going to have to get a lot closer than I'm willing to try.
 
Effective range? Pretty darned SHORT! In one of the tests I found on the net, some examples, using various ammos, the HP bullets didn't go much farther than 4' -- which suggests it wouldn't do much damage, either, against anything or anybody UNDER WATER. One test of BALL .45 ammo hit the 4' distant plywood board that was the target, and penetrated, but didn't go through. (Expansion is NOT a plus when shooting underwater.) These guys are using a 1911 in .45.

I think the Glock maritine cups are designed to allow the gun to function AFTER being in water, when water might still be in the action, etc. The shooter in this series uses a Glock 22.

Here's another video about the EXPERIENCE of shooting underwater.

Water is pretty thick/dense compared to the air we breathe... and that difference probably plays a roll is the harsher recoil addressed in the following vide: things aren't happening as quickly, the gas can't dissipate as easily, etc.

A common method of recovering a bullet for ballistic testing is to fire into a barrel of water. For that matter, ballistic gel is mostly water. Water slows bullets very rapidly. If your foe is big enough to need a bullet, you are probably looking at contact range to a few inches away for it to have much effect. Bang sticks, used against sharks, are contact weapons - a shotgun shell and firing mechanism at the end of a pole.
 
Sounds like in addition to maritime cups, a stronger striker spring would do well to improve reliability of strikes in water.

A stronger striker spring was included in the kit I purchased some 15 years ago.
