Can A Firearm Shoot Submerged/In Space?

Post by ScottDLS »

I've wondered if a modern firearm could function underwater. I'm leaning toward NO due to over pressure from water in the barrel. In space (i.e. a vacuum). Yes?

Didn't Glock have firing pin cups that facilitated firing under water?

I think modern propellants have enough oxidizer that you could fire a gun in space, although remember Newton's laws.

pistol calibers aren't going to do very well underwater. You might way to try .223 or .308.

The chemistry of smokeless powder is considerably different than charcoal, sulfur, and saltpeter. But the premise is true, a gun does not burn atmospheric oxygen, propellants have their own.

......which is why rocket fuel burns in space.......either as a hypergolic reaction between liquid propellant and a liquid oxidizer, or as solid propellant which includes its own oxidizer.

I recall an episode of Myth Busters, in which they fired a Garand into a swimming pool to see how far the bullets remained lethal under water. It was an amazingly short distance. The FMJ bullets repeatedly fragged themselves after traveling a few feet.

Good to know, I will be sure to not shoot BG from under water, but I'll bet I could hit them from several hundred miles away in space because the bullet won't slow down too much.
I hope I don't have to add underwater, or space travel to my practice drills.

Mon second though maybe a harpoon is the right tool for the job.

Correct, I have a set or two around here somewhere I intended to install but forgot to
https://www.amazon.com/Glock-GLO70M-Mar ... B007DZV7SE
Factory OEM Glock™ Maritime Spring Cups for underwater firing of your Glock™ pistol
These are NOT aftermarket parts, they are factory Glock™ components.
Enable your Glock™ pistol to fire underwater and in extreme hostile environmental conditions
If water or debris get inside your Glock™ firing pin channel it will still function and fire
If I recall, you must make sure the entire pistol is water filled, and has no air pockets so the water pressure is constant
I bought them in case my kayak got flipped by a shark ... :willynilly:
I only kayak in lakes around the Hill Country and I saw that pistols don''t fire long distances under water, so I never bothered installing them.

I think the actual only reason to install them would be if like I went swimming and came out of the water then the firearm would still work.... perhaps
Like Designed for Navy SEAL operations contract maybe when they competed with Beretta
