Can you fire a gun under water?

Answer 1

yea but the bullet not going to go as fast

Answer 2

As all metallic cartridges are waterproof for short periods of exposure to fluids, ANY firearm WILL fire underwater, but, as water is several times denser than air, the bullet will lose velocity very rapidly, and actually come to a complete stop. Also, a weapon with a longer barrel, a rifle or shotgun, if the barrel is filled with water, may burst its' barrel from hydraulic overpressure when the gas pressure from the fired round impacts on the fluid confined in the length of the barrel, as it would if the barrel became obstructed with mud or any other solid matter.
This also happens if weapons are fired into the surface of water, as well.
In fact, forensics labs and other firearms testing facilities use water tank 'bullet traps' to recover projectiles from test firings, where the bullets are undamaged, or only slightly so, from impact with the contained fluid.
You can see this quite frequently on TV on such such programs as N.C.I.S. and the 'CSI' clones.

Answer 3

On some guns you can... Yes but it would not be very effective.

But a SPP-1 was desgined to shoot underwater.
SPP-1 is a non-automatic, manually operated handgun with four barrels. Barrels are hinged to the frame in the same manner as on break-open shotguns. For reloading, barrel cluster is tipped to expose chambers, and four cartridges are inserted into barrels. To speed up ejection and reloading cycle, cartridges are loaded using flat clips, made from steel. The double-action trigger unit consists of a striker, mounting on a rotating base, so during the each trigger pull the striker is ****** and simultaneously rotated to the next, unfired barrel. The single lever, located at the left side of the frame, controls the safety and reloading. It has three positions, top for "Reloading" (barrel release), middle for "Safe" and bottom for "Fire".

To be effective underwater, SPP-1 uses special proprietary ammunition, with rimmed bottlenecked cases 40mm long, sealed from water. Unusually long bullets are made from mild steel, and are drag-stabilized underwater; on air, bullets are not stabilized at all, so the effective range "above the air" is limited, but the "lethality range" is about 15 to 20 meters. When underwater, lethality range degrades with the increase of the depth: at 5 meters depth, the effective range is about 17 meters; at 20 meters depth, the effective range is only about 11 meters.

Answer 4

O.K., you are a SCUBA diver under water. Let's assume your bullet is water proof. Your gun, either a revolver or semi auto, is in a water proof bag. You pull the trigger. The gun will go off, the bullet will rip the bag, and go, depending on the power of the round, a few feet.

Now let's assume your gun is exposed to the water. The bullet will still go off (it's water proof). But what happens with the bullet hits the water in the barrel? Water will not compress but is a liquid. So, the bullet should push the water out of the barrel but lose some of its several foot range.

Worst case scenario is the barrel is so long that the bullet can not push the water out of the barrel before pressure bulges or ruptures the barrel.

Answer 5

Mythbusters did a great show on this one. Based on what I saw there dont EVER fire a shotgun under water as it will blow up due to water filing the barrel and the tremendous compression.

They fired some pistols and rifles pretty well though. Check their website.

Answer 6

Yes you can but it is NOT recommended.
Some guns will function under water. See links below.

Although the gun will function and fire, the effectiveness of the bullet is greatly reduced, but I wouldn't want to be the guy being shot at just to verify that for you.

Answer 7

i have never tried but i think you can fire a gun under water

Answer 8

No. Depending on what the round is and velocity your projectile will not reach the end of the barrel. Soon as the round hits water it breaks up (super sonic rounds). So assuming your gun is underwater and submerged it will most likely break up possibly damaging your gun. The fact is that soon as it ignites the gas expands and with no direct way out you will really damage the gun possibly hurting yourself.

Answer 9

yes but it would only travel a few feet before the bullet stopped i seen an episode on mythbusters were they proved it

Answer 10

not all bullets will fire or gun designs
fire under water

Answer 11

certain guns... the glock issued military ones can... regular guns can because the gun mechanism doesnt have enough oxygen to release the pin through and it is slowed down so it may not fire... you need air so it fires without a counter element in the way
