Will a Glock shoot underwater

Answer 1

A Glock may be fired underwater, but irreversible damage will occur to the barrel. This damage is caused by the water present in the barrel: as the bullet is fired, the expanding gas and the physical size of the bullet will be forced against the water inside of the barrel creating a bubble-like impression that will pose serious danger to any subsequent rounds fired. There is also a specialized Philippine GLOCK 21 Mariner model which is altered for underwater capability. cf. This video is proof of a GLOCK fired underwater: http://www.YouTube.com/watch?v=Dvgu3VaO8sE

9mm Glocks have thicker barrels per pressure than 40 cal or 45 Glocks, and the latter are more likely to suffer catastrophic failure. All air must be out of the gun before firing. Full-metal-jacket ammunition must be used as hollow-point ammunition will expand in the barrel. Your maximum range will be a few feet, and your accuracy will be terrible. And after all that, there is still a chance your gun will break.

If that isn't bad enough, your hearing will be permanently damaged (the shock waves are about 4 times as powerful in water as in air), and shock waves reflecting off of hard objects (rocks, etc.) may actually damage your internal organs.

And on top of that, the water slows slide movement and ejection, so the gun will probably malfunction on the first shot.

All that being said, if an alligator was dragging me underwater and I had a Glock, I'd shoot the alligator. What do you have to lose?

Answer 2

From what I've read and seen on you tube, any gun will fire underwater at least once. :) Glock makes mariner spring cups so that no water can get into the firing pin chamber and hinder follow up shots. They designed these for the glock 17 in 9mm. Some dive teams have reportedly carried these to upset sharks. ;-) The round goes through a 1/2 inch pine board at 10 feet. The .40 cal of the glock 22 is a hotter round putting more pressure on the gun and increasing the likelyhood of damage to the firearm and user, so I've heard. It is never recommended to shoot a gun underwater even if the gun is equiped. Some rules if you need to are: 1. Make sure gun is fully submerged, no air pockets in barrel. 2. sound is louder underwater use protection. 3.a. Use only full jacketed ball ammo. b. For best results use primer sealed caps. c. Use low velocity rounds, best is 9mm, .45 is also said to work but slower. 4. Sound bounces off objects and can cause internal trama i.e. bleeding if user is not in an open area. 5. Please don't try this at home without wearing a "stupid" sign. I'll never shoot my Gun under water, but I feel like more of a man knowing that I can. Scuba Steve

Answer 3

Most firearms will fire underwater, at least once. Properly fired, with the marine springcups and sealed ammunition, Glocks can be fired in semi-automatic mode underwater. This should only be done by trained professionals.
