Glock Boiling???

Same reason that any product produced for more than five minutes undergoes revisions: Designs evolve over time to make improvements or meet new customer expectations.
 
You know, what is it about Glock folks that they believe anything?

I have noticed a LOT of BS threads related to Glocks.

A LOT.
 
I use MSG to tenderize my plastic guns. Just saute in butter with a dash of garlic and MSG... Nice, but you do get hungry after a range session!
 
This thread reminded me that I need to ask my mechanic to change my tires over from winter air to spring air soon.
 
These condensed time tests (all) are valuable but the one important thing they lack is actual time.
First of all, while the oldest Glocks have yet to work their way into their third decade, nylon has been around for just shy of 80 years. There's really no mystery about what happens to nylon when it gets old.

Second, the UV test wasn't designed to determine the effects of aging, it was to determine the effects of UV exposure. The amount of UV exposure was quantified into something that would make sense to persons interested in interpreting the test results, but time wasn't really a tested parameter in the experiment.

Third, the condensed time tests are actually pretty useful. No one would spend the money to do them if the results didn't provide useful data. And as pointed out, they've had 8 decades of experience to determine if the condensed time tests are providing accurate results or not.

Finally, I'm always somewhat amused by these threads implying that high-tech engineered polymers are likely to self-destruct with the passage of a few years. I can still remember when the biggest worry about plastic was that the planet would be eventually inundated by essentially eternal plastic waste.
I'm not a Glocker but why are they on generation 5 after 30 years?
First of all, they're on generation 4, not 5.

Second, it's only been about 25 years.

Third, none of the changes in any of the generations had anything to do with changing the polymer frame material--the topic currently under discussion.
 
1. You had a problem with your Pearse grip extension. Taking the advice to boil your Glock is analogous to calling Goodyear when you have a flat and they advise repainting your car. Dump the Pearse extension and go with a different one.

2. Plastic CAN rehydrate. Soft daily and extended wear contact lenses are hydrophilic (water loving) and if allowed to dry out will crack and shatter. Glock frames, mags and parts are not made of a polymer anywhere close to the stuff contact lenses are made.

3. It is possible that what the Pearse rep was having you do was heat the plastic to allow the rounds to stack correctly.....the boiling wasn't to "rehydrate" but to prevent you from melting it in the oven, microwave or with a heat gun.

4. It is also possible that he's pulling your leg.
Answer number 3 was the only plausable rational I could come up with as well.
 
If you add some garlic, a bay leaf, tomato paste and sauce you might be able to serve it with spaghetti.
 
No the reasons given were to rehydrate the polymer and return it to it's original dimensions. This would take up the extra space and allow things to fit properly. If you read the explanations of those that understand this process in earlier posts you will see that the polymer will expand a small amount.

While I don't think rehydrating a Glock is a must, it is ignorant to fail to understand the truth behind the theory.

I know many compare this to blinker fluid and the like. I fully appreciate the humor in that. It does sound kinda weird. :)
 
The magazine has a metal liner in it anyway.

Even if you could "Re-hydrate" your Glock (you should try boiling it in Gatorade... the Glock might need electrolytes or protein it sweated out too :rolleyes:) it would not impact the internal shape of the mag.

Occassional rattling of rounds is normal. You will not be able to boil out the rattle. Repeat: Boiling of the Glock will accomplish nothing.... except maybe provide for my continued amusement.
 
Back in the day we used to boil suspension arms of our remote control cars to make them less brittle...seemed to result in less broken arms.
 
Boiling your polymer firearm parts is a bad idea.

Boiling the frame as some do is really stupid.

Some people in the thread are citing the melting temperature of the material, as if that is the temperature required to distort it. That is not the case, the melting temperature would turn it into a distorted mess. However you can cause the material to stretch and the internals and components to shift and be out of spec by softening it at a much lower temperature than the melting temperature. In fact you can reshape the plastic at lower temperature with pressure, and there is springs and weight and material stresses and similar pressures already present in the firearm.
Even if it works after you may have dimensions and gaps internally that the firearm was not meant to have and is functioning less safely as a result of.
You do not need to change the dimensions of the frame much or even to an extent that is visibly obvious to have made it less safe or less reliable.

If you are going to boil a part which is stupid, at least use a double boiler so the thing is reaching a certain temperature uniformly, and the portion touching the bottom of the pot is not much hotter than the water itself.

I can just see some poor guy with a used gun not know the previous owner boiled the gun and distorted the dimensions of the internals slightly.
I already don't like that some people use a dishwasher, some of which have cycles approaching boiling, not to mention covering the internals of the dish washer and your dishes in current or future loads with lead that you shouldn't be consuming. But actually boiling it submerged at such a temperature is far worse.

Only in the schools where the rich or well off attend. The rest of us fend as best we can.

The temperature required to remold the gun frame would have to be much higher than 212 deg I would think. The mag I boiled was slightly more flexible but was not anywhere near malleable or distortable. Glocks operate in temperatures over 212 degs just fine. It would take a pressure cooker to change the way it's molded or formed.

I hope that with a statement like
Do they still teach math and science in high school?????
You understand that this is a fact. Right? It has been shown here by those that understand the process; that not only will polymers, like those used by Glock, take on water but they will increase in size as well. Boiling has also been stated to be a very effective way to hydrate a polymer.

The need for this has not been quite so clearly documented. The science is right though.

P.S I don't know what kind of math and science they teach in high school, I got a real world education as a homeschooler. If we didn't understand something we studied it out until we found the truth.

Boiling it just boils all the nutrients out! I prefer to bake mine with butter and lime, or even grill it over a spit. Make sure you put BBQ sauce on it to keep it moist!
 
Depending on the altitude. :)


I can answer this question: "Do they still teach math and science in high school?????"

We don't needs no education no more.
We gots the internet.
 
Glocks aren't made from a polymer that will gain anything from water.

Boiling a Glock, if anything, will cause the plastic to more likely lose some of it oils that keep it plastic. You're far more likely to dry out the plastic and hurt it.

Heating certain polymers in an oil bath can be a good thing. But not your Glock.

I guess I don't understand what you mean by "oils that keep it plastic".

Glocks aren't made from a polymer that will gain anything from water.
In earlier posts The glock polymer has been identified as nylon 6 or 66. Each can retain water. They will also gain thickness as is stated by a professional below.

Just a follow up on the Glock boiling subject. BASF has on their website a technical paper entitled "Mechanical Performance Of Polyamides With Influence Of Moisture And Temperature". Polyamide is the technical name for Nylon. The people on that thread should read it. Among other things it states that for every 1% of moisture absorbed there is a 0.2-0.3 % increase in dimension. This would amount to .002 - .003" per linear inch. I don't know about Glock or the Pearce magazines but that can be significant if you are concerned about tolerances in a precision assembly.
 
Depending on if the polymer is nylon 6 or 66 or a blend, it will melt somewhere between about 425F to 500F. Nylon doesn't gradually soften as it is heated like polyethylene; it suddenly turns into a liquid like state when the melting temperature is reached.
 
And if it does absorb any water it it not likely to do so uniformly and will distort in shape.
