Dive knives when out with a DM

[Nemrod]

That was a 1911.

I usually make my way to the Jupiter area at least once per year and I am amused at how many divers I find with the huge knives strapped to their calves. And it is mostly just there I come across this, beats me. Last summer I got my hair tangled in my necklaced bungee strap and could not find my EMT scissors and so I asked for any to loan to cut the bungee. Suddenly, as if from no where, a dozen huge BFKs appeared! I only want to cut a bungee, not behead myself I exclaimed! A kind lady offered to cut my hair with her rescue cutter and I further declined that offer. So, in desperation, I pulled my razor sharp Tekna knife and asked the lady to cut the bungee strap, not my hair, please. And I cautioned her that the knife was very sharp. She then, with great skill managed to cut the bungee freeing my golden locks and then cut herself (fortunately like a paper cut), no stitches were needed for either party.

Yeah, on a dive boat, Jupiter, Florida, I asked for some EMT scissors and all that was present were BFKs and one very sharp but comparatively tiny Tekna knife . My EMT shears were MIA.

I hate it when my chest hair gets tangled in the regulator bungi, too!

A Glock will fire underwater with maritime spring cups although they are really more for an over the beach scenario when the striker channel a still water-logged so the water won’t hydraulically impede the forward motion of the striker.

I have a 19 with maritime cups but haven’t carried it underwater. Someone on the internet modified one to fire blanks and was killing lionfish with contact shots.

I didn't think that guy was using blanks. And a G19 will fire and cycle underwater even without maritime cups.

I have a G19 and a pool and got curious one day...

Please mount a GoPro to your firearm and upload at your next opportunity

A Glock will fire underwater with maritime spring cups ....

Maritime spring cups have nothing to do with firing underwater. [In spite of lots of interweb ex-purts" saying that's for what they are intended.] They were designed to aid in draining water from the rear of the firing pin channel should water get inside there. Primarily designed for duty carry of pistols carried in wet/splashy environments.

Water ahead of the firing pin, um, "striker" in Glockspeak, will drain from the weep hole (that is NOT an oil hole on the bottom side of the slide!) or the FP hole in the breech face; water behind can easily drain rearwards if you tip it muzzle up. Water behind the FP will drain, just more slowly. Gunk in the FP, er, striker, channel is a bad thing. That's why there should never, ever, ever, ever, ever be lube placed in there. (Weep hole, not oil hole.)

Would not be firing one underwater. Can be done [with or without maritime spring cups]. But sound travels much more fasterer and with more percussive impact in water than in air. And I suspect that the effective range would be measured in very few feet, not yards. (Mythbusters "Bulletproof Water" Season 3, Episode 21, aired 13JUL05)

It would drain from the debris hole but as I stated above, its primary function is to help the firing pin move freely while there is still some residual water in the channel. Over the beach scenario is what the .mil calls it. Think coming out of the water but before your weapons have properly drained. Navy SEAL type **** and beach landings.

Firing underwater would be good only at contact distances. The bullet will be unstable as soon as it leaves the barrel while encountering massive drag.

They, the maritime cups, will, however, let certain model Glocks fire and function underwater.


The Russians have an underwater rifle that fires special ammunition more akin to darts. Much more range:

I know next to nothing about these. Your comment motivated me to get a bit more educated:

It actually is a 1911A1. You can see the arched mainspring housing in this shot:

Good eye!

Yes, my 91-year-old dad is ret. U.S. Army (30 years active duty regular Army), and his military sidearm was an M1911A1--so, I know a tiny bit about them (though next to nothing, really, as I wrote above). But it wasn't until this thread have I thought about the differences between the (original) 1911 and the 1911A1. Imagine: A thread on Scubaboard!!

The switch from 1911 to 1911A1 happened six years before your dad was born

Original 1911s are pretty much collectors' items at this point. I doubt anyone is carrying one regularly. But it was worth a look as movie studios and prop houses have some oddball old firearms so you can't really assume anything.

This is fun. It's how I got started on the internet, answering questions on rec.guns in the mid-90s.
