Compared to their steel framed counterparts, Plastic frame handguns are a relatively new on the scene, they haven't been around all that long.

So I was wondering, just how long will one last? do you think some day way off in the distant future your grandson or great grandson may inherit grandpas Glock? or do the plastics in a Glock and similar pistols have a definite life span that is way shorter than their steel counter parts?

The reason I ask is that, I came a cross a story about Glock that was well cared for but the plastic frame started to crumble after 20 years. You may have heard the story too...maybe true maybe not. Thing is it started me to wondering, just how long will a plastic framed gun last? lets say under ideal conditions? Do you think they will outlast a steel framed pistol say like a 1911?

i remember some journalist put 150,000 rounds through a Glock 17 and only needed to change out magazine springs.

But then he found that if you only put 15 rounds in the magazines, they last a lot longer.

i forget where i read it at. i will have to google it later

That's nice guys put the gun in buckets of sand and mud. Freeze it, thaw it, dunk it in the ocean. Fire a life time of round in a few days. All these BS parlor trick "Torture" tests prove nothing when it comes to the physical and chemical changes that can make plastics turn brittle as a result of age. Only time will tell wether or not these polymer will be as duriable as there metal contempories.

As far as those torture tests they been doing that stick since the 70's in Gun Digest. Most of the weapons passed the same tests, especially the 1911's and revolvers. So what Glock does as proof only impresses the ignorant.

Accelerated testing techniques can't even estimate most advanced polymer "life expectancy". Unless pulverized/melted with explosive/heat forces, there will be intact polymer laying around long after all the metal has disintegrated, perhaps even for the 4.5 billion years Earth has remaining.

And not just Glock polymer either, of course.

But that doesn't take in to account if it will still be usable. Yes, it will remain plastic long after steel has turned to rust. But like one person claimed, IF it starts to crumble after only 20 or so years versus great grandfathers 1911 or .38 special that remains shootable there could be a problem.

Its a Glock! i have friends that have fired 15k rounds and they still function. I was told when i bought mine that the barrel and springs would last atleast 10k rounds before they need to be replaced.

You'd still have to prove it to me and alot of other skeptics out there. Granted I'd like to find the source of the crumbling gun frame. And see it for myself. But as far as plastic being a superior to steel weapons material only TIME will tell. Nothing else.

The article about the crumbling Glock frame with a photo is over on The Gun Zone Site under their Glock pages... It was a Glock 19, that made it 18 years and then unexplicably started to give up the ghost...I understood it to be an exception and not the rule...

I agree with your assessment that torture tests are basically parlor tricks...

We know that gun steel if properly cared for, will last a very very long time, they have a proven track record...Plastic is a relatively new commer, and while it doesn't rust it is succeptable to UV radiation, as is all plastic...Then there is the issue of long term exposure to solvents, what will be the effects of such things after say twenty or thirty years?

it's true that the latest technology in polymer science has far advanced in the past 20-30 years, but i may give you a little insight on polymer manufacturing; for almost 9 years i carried 24tons of sulfone(base product for a grade of polymer) from Georgia to Ohio every other day and I learned a little about the process. The chemical process is much better now than just a few short years ago, which means the polymers don't degrade near as much as they used to; for example the dashboards and headlamp assemblies in your vehicles, they don't fade and crack the way they did ten years ago. If I had to bet, the Glocks manufactured today, using today's technology are far more superior than technology used 20-30 years ago. It's probably safe to say that the older Glocks will deteriorate at a must faster rate than will the newest Glocks

They Last Forever!!!!!

Just like Woody Creature says they last and last. I've had my Glock 22C since about 1988 and I wouldn't part with it even now. It just keeps on working and working for me. I love it.

I agree they'll last forever and you're probably right that they will hold up to the test of time, but only time will tell if they will function properly, the question is if the older models with older polymer technology forsaw the durability problem with the age of the plastic

Well, that's just great. They could change the name of this site to ," MORE stuff you need to worry about". I have a generation 1 G17 I got about '86, does anyone want to volunteer to properly dispose of it for me ? ;)

Out of the 8 I own,three 9s(17,19,26)10mm(G20),.40(22&23),45acp(G21) and the .357(G31).The G-17 given to me a highschool graduation present has been the Timex of them all while closing in on 100,000 rounds,only modifications that have been done to it are a Aero-tek titanium guide rod,a 3.5lb trigger connector and 3rd set of Trijicons and Hogue handall,this has been one outstanding hangun and continues to serve me well.

I am not laying a knock on Glocks or any other plastic framed handgun...The do work and work quite well under a variety of conditions.

The question is longevity of plastics over extended period of time. I have never seen a 60 year old Glock...but on any given day at the range I see several rifles and pistols that are easily over 60 years old and some closer to 100 years old still working.

When one buys a steel framed handgun they have a reasonable expectation that the thing is going to last for a very long time. There is history to support that expectation.

The same cannot be said about the plastic framed guns because the history isn't there to support the expectation. They have not been around long enough for history to answer that question.

This is not a bad thing, it is just a lack of history.

Doesn't it just give you that warm fuzzy feeling of being a lab rat "Beta" tester that pays with there life if "they're" wrong!!:thumb:
