I know the standard OEM spring cups goal is to hold the striker in place during firing and cycling, but how does the maritime spring cups assist in underwater shooting?

Can maritime spring cups be used long term just as the standard? Just curious.

I would like to know too

It looks like it lets water out of the gun as opposed to the solid cups which could keep trace amounts of water in :dunno:

 

[Glock4President]

I think it let's the water pass through. You see how the maritime one has plastic cut out? I think, but I could be totally wrong.

These aren't designed to let the Glock fire under water - they are designed to allow water to drain out of the pistol after it has been submerged (namely, the firing pin assembly as it sits within the channel liner).

Why does anyone want to fire a gun under water? The bullet travels only about 4 feet under water.

 

[cs133atom]

They insure that water can pass by the firing pin within the firing pin channel, thus preventing the creation of hydraulic force within the firing pin channel -- which would slow the firing pin down, causing light primer strikes while operating in wet locations or after emerging from being submerged. **a bit of an insurance policy**

correct...made to let water drain so as to not create extra pressure that could possibly make gun blow up

not to shoot underwater

 

[phil evans]

maritime cups made by glock for very specific purpose, to permit water flow both ways, when black missions are off landed in wet envrionments, i.e., marsh.

Glock says they are for the G17 only. Not sure why.

The special cups could also be beneficial if you want a gun in your canoe or kayak for boating in rough water or in the Everglades. I think the cups are just fine for normal (dry) use, too.

here is a FAQ page the last question has a detail answer about maritime cups

These are all correct. Their main purpose is to limit the potential of water or other foreign liquid from causing the firing pin to have a light primer strike. It allows the water/liquid to drain out.

So, if I were to install maritime spring cups on my G19, would I see any difference in reliability, primer strikes, durability, etc? TopGlock link mentioned that they're made for the G17. I wouldn't even dare try shooting underwater. Just for kicks. I know, I'm weird. Even Glockmeister says they're selling them as a 'novelty item'.

From Glocks website...

MARITIME
Optimum water permeability for secure firing even under water!
Only approved for GLOCK pistols in caliber 9x19.

Yes they will wear out faster than standard cups.

 

[jedi573]

The normal cups get replaced on regular intervals for armoror-level maintenance. There's less material to work with on the maritime ones; they arguably wear out faster than the conventional ones.

The standard cups will act like a piston trying to compress water. The maritime cups are relieved to prevent that.

Nope. Maybe see reduced reliability though.
I have a set for my G17. Never installed them. They are spare parts for now.

I would think firing underwater could severely damage your ear drums if you're underwater as well

From the Topglock website:

"Another reported case was the Glockster who decided to try out his Glock 23 .40 S&W in the swimming pool after seeing pictures of Glocks being fired underwater on the web. He was totally submerged, with the gun, as he fired at a piece of wood on the bottom of his pool. The Glock did fire, the .40 S&W FMJ round left the barrel and went into the wood. The chamber also exploded and implanted shrapnel into his leg. Thinking that the water would muffle the blast, he did not wear hearing protection (the blast is actually about 4 times louder underwater). He is now mostly deaf in one ear and hears high-pitched tones most of his waking life."

The topglock FAQ on the subject is a pretty informative read.
