 What is the expected lifespan of the plastic on a Glock?

Under the best conditions or worse conditions......all plastic degrades over time.

I have no issue with this....I own 4 Glocks.....but how long can they be expected to last?

My most used Glock was made in April 1989.

If taken care of, it should last forever.

The black anyway. I've heard dye can cause deteriation in sunlight (same with pmags).

they are biodegradable 25 years and they turn to dust

no plastic is forever...and I'm sure they have done studies on degrading.

I was just wondering......I feel my kids will eventually get them.....but was curious about the grand kids.....

If Christopher Columbus dropped a milk jug on the beach the day he landed on America, it would still be there today... I think its safe to say that your Glock will outlast you, and your children, and your grandchildren, and so on.

The remains of the bottle would still be there.....would it still b e functional as a liquid vessel?.....probably not.

Probably not. But the polymer used in Glock frames is not comparable to throw-away plastics.

Bingo!

The plastic degrades and loses it's form, but the individual plastic molecules remain for eons.

GLOCK's are resilient firearms. I love them.

I love mine too....they can be abused....neglected and they still run like a scalded dog.....I wouldn't trade them for anything.....just wondering about longevity.

I've bought my Glocks as tools....not collector pieces. I shoot the hell out of them....and they are great...

I don't think any Glocks have died to to plastic deterioration yet. I expect that the springs and small parts will go first

I believe that glocks are not plastic, they are polymer which is entirely different.

Like Kansas sang, "nothing lasts forever but the earth and sky" however, I think your glock will out last any memory of when it was purchased.

I thought by definition....that's what plastic was.

The biggest cause of plastic deterioration is sun light. just keep it on you concealed and it will last forever.

Not hardly, every jug I use for watering degrades, cracks and starts to break apart in less then 6 months in the sun. Without a UV stabilizer, plastics will start to break down when exposed to sunlight.

Artificial aging tests have been done on Glock frames and the results showed no discernible degradation of the polymer in a simulated 500 years.

Most peoples Glock's have never even seen sunlight.

This is what I was asking.....thanks.

I'm sure that is pristine conditions....not locked in a car 24/7 in Fla.....but heck....if it last a solid 100yrs I'll have gotten a bargain....

The plastic parts are replaceable. It probably will never be an issue, but it wouldn't be the end of the world if the plastic did crack or degrade.

Polymers are often kept at elevated temperatures, in order to accelerate chemical breakdown. Environmental chambers are often used.

An environmental test chamber artificially replicates the conditions under which machinery, materials, devices or components might be exposed. It is also used to accelerate the effects of exposure to the environment, sometimes at conditions not actually expected.

These conditions may include:



http://en.wikipedia.org/wiki/Accelerated_aging

http://en.wikipedia.org/wiki/Environmental_chamber

The EPA says that plastic bottles, disposable diapers, plastic bags and fishing line take 450-600 years to degrade; and that's while floating in the ocean!

I'm pretty sure Glock's Perlon is a better polymer than what's in diapers.

A)That was steel that failed.
and
B)
Serial is EVX5xxUS
That's why.

At approximately 100,000 rounds the frame rails will need to be replaced.

Well just have to wait for Glock's 100 year birthday to see for sure.

You sure that wasn't a Gen2?

Bakelite is an early plastic that has been around for over a hundred years. Sunlight may break it down quicker but I doubt any of our Glocks are exposed any appreciable amount.

Except for those police trade-ins.

Yeah right. Seven and a half hours a day in a car isn't causing that much "damage".

IIRC, modern water jugs are designed to break down in less than 6 months.
