Glock 17 Maritime Plug: What's the deal?

HMMurdock · Apr 18, 2009

What's up with the "maritime plug" http://www.ghostblock.com/product/GHO_MSC/Ghost_Maritime_Spring_Cups.html for the Glock?

The research I've done says that it'll improve the Glock's reliability in watery and other harsh environments and it was only designed for the Model 17. I've also read that "some teams" use their 17's with the maritime plug to "dispatch sharks" which, frankly, I don't believe.

Does anyone know if the plug does anything for your Glock and if it does, indeed, only work for the Model 17?

There is a lot of hype and whatnot about the Glock and it's mythical powers underwater *cough* bullcrap *cough* but research of a lot of foreign military amphibious teams do, indeed, use the Glock 17. Anyone with real knowledge on this care to set me straight? Appreciate it.

Ive seen condoms over the barrel to keep the rain out and that is where it ends.

Going underwater is not an option for me.

According to the video he's using a 19... and awesome video, by the way. Thanks.

glocks dont work underwater. ive got a couple of vids. of all the pistol that was shown to cycle properly, only the beretta 92 and the springfield 1911-a1 were able to fire 4 shots successfully in series. glock and sig meanwhile failed to cycle after the first shot.

I would guess that they say it's only for the 17, because it's probably a bad idea to fire a larger caliber underwater.

Maritime spring cups, as they are called, are supposed to keep water out of the firing pin channel, which would impede the firing pin's movement, thereby preventing the from being fired.

My understanding is rather the opposite of the above. There are relief slots cut in the maritime cups to maintain adequate firing pin pressure thus preventing light primer strikes by allowing a channel for water to pass through and preventing hydraulic pressure from slowing firing pin travel.

That's what I've read.

They're not for underwater firing, they're for firing after being submerged.

P.S. they fit all Glocks.

They are for letting water flow into and out of the firing pin channel. Underwater you need the air out of the gun so that it operates uniformly. Then the G19 and G26 will indeed fire and cycle under water.

Do a youtube seach for glock underwater in garbage can. I didn't find it yet but I did find http://www.youtube.com/watch?v=Dvgu3VaO8sE&feature=related

Is there anything Glock didn't think of?

So a maritime spring cup will work just as efficiently on a Glock 19 as it would a Glock 17?

Yes.

We have a feature length video of underwater shooting. Glocks, 1911, shotgun, SKS, AR-15, revolvers, BHP, SIG 228. Glocks do fine underwater and yes, we have used hollowpoints UW. Here's a G17 shooting a hollowpoint into a jug of water, underwater...

And here's a G26...

The maritime spring cups work in all Glocks regardless of caliber.

here ya go

"MARITIME

I never could figure out why shooting underwater was such a good thing.

In the vid posted above, the milk jug was shot from about 3ft away, if that, and it didn't go through the other side. I'd take a .25 on land over a 9mm underwater anyday.

I never could figure out why climbing mountains or jumping out of airplanes was such a good thing either but people seem to do it quite a bit.

That's because it seems that all you know about UW shooting is what you saw on one little clip. The bullet you saw was a hollowpoint and would only have traveled 5 or 6 feet even without the jug. 9mm FMJ, depending on manufacturer, will travel over 20 feet and will penetrate 1-1.5 pine boards at 3'. With all that being said, the test had nothing to with defensive shooting so it's pretty irrelevant what the bullet does or how far it goes.
