I just had my dealer send and OD frame G17 back for a new one.
The frame was cracked from the lanyard hole to the frame bottom.
Is this just an anomoly, or are the green frame Glocks more suseptible to this than the black one’s?
What got me to thinking this might be a possibility is the thread about the different colored Magpul mags.
It was brand new, I had it in my possesion less than 24hrs, so the dealer is replcing it with another new, OD framed one.
I realize functionally speaking it would have never affected anything, other than not being a very strong lanyard attatchment.
Now I have to wait until I get back home from work, another week, to get the other new one.
Thanks, Terry.
One last thing, I don’t know what distributor my dealer uses, but the lady told him that there have been other reports of this happening.
I have no way to varify this, so if my edit is out of line, please remove it.
I haven’t heard anything to indicate that OD-framed Glocks have a higher incidence of cracking than black ones. And fwiw, quite a few people I know who worked or currently work at Glock opt for the OD guns.
Unless broader data becomes available showing a trend, I’d chalk this up to an anomaly.
how did it crack? did it come from the factory that way?
I have seen claims, in a “Glocktalk” thread that quickly spun out of control, and then in the recent M4 thread on the durability of colored PMags, that black colored plastics have high levels of “Carbon Black” that helps protect them from breaking down due to exposure to UV rays. I certainly am not an expert, is anyone here an expert on thermoplastics who can confirm or deny this?
FWIW for the original poster, I have seen pictures of black colored cracked Glock frames.
I know the claim is to be made for solid vs translucent, but i would be surprised if Glock would put out a sub-par polymer. But i have been wanting an OD G20, so now i am going to keep my ears open on this.
While I’m no means an expert but as it was explained to me, by making a part in a color other than black it “dilutes” the mix a little bit relative to a straight black one.
The difference in strength isn’t enough for me to worry about, but if you hypothetically did a stress test between a black and a colored part, the black one would be slightly stronger or stiffer, but again, not enough to worry about.
Anecdotal evidence, my Tan Pmags have slightly more flex when squeezing the bodies than my black ones. Do I give a rat’s ass? Hell no, they all work. However, if I was less vain and more paranoid, I’d get all black.
MisterWilson explained it properly. Black plastic is, as a rule, stronger than otherwise identical plastic that has been modified to be another color. But it’s “stronger” in the sense that while The World’s Strongest Man is far stronger than I am, we can both lift a pencil equally well.
In other words, it’s not an issue of which is “stronger” … it’s an issue of whether the material is adequate to the task. There are stronger materials that your AR/M4 could be made out of, too.
The dealer replaced it with a new one, but he forgot to take the trijicons off, so I am getting the warrens for $20.
I have no idea when the crack developed.
Just chalk it up to an anomoly.
Thanks for the help.
