Help! -calling all "glock"-sters

[MrChubbyMcLard]

Hello,

I'm a first time poster seeking information......

Below you'll see pictures of a Glock 27 I own.......

It seems there's an abnormal groove.......Not sure whether it's damaging the pistol's frame........


Has anyone here experienced this same problem?.......What was the outcome?.....

Hopefully the pictures below expand when you double click on them.....

Sorry.......I've owned this pistol 8-10 years........Probably have put around 2,000 rounds through it......if even that.......

I own a 27 but the one you have looks a bit different....What generation is the one you have?
The only issue i had with mine was the slide spring broke but it was due to out sourcing and inferior material...Glock fixed it free of charge.broke at about 600 rounds.
Anyways,best thing to do is take it to your local "reputable" gun smith.And if possible up grade the slide spring because the up grade is much stronger.One of my springs came over the retention lip.the up grade wont do that.

When did you first notice this? Is it getting progressively worse?

At first thought it appears that it's done all of the scraping it's going to do and there's nothing to worry about. The "groove" isn't on an area of the frame that is taking a lot of stress. Think of this as a callous on your foot.

What it looks like is that at some point the recoil spring/rod was not in the correct position on the barrel. My Glock has two steps and the guide rod must be on the step closest to the barrel or the slide cannot be installed. With the new two spring guide rod with the smaller dia on the barrel end it looks like it allow it might go together incorrectly. Your spring/guide rod looks bowed out to me in photo #1. The correct slot on the barrel has a semi-circle cut where the first step is a straight cut. The other step would allow the guide rod to hit the frame.
I have wondered what keeps the guide rod on the correct step once the gun is assembled; maybe it’s this tight tolerance to the frame. I would assemble it correctly, shoot it and disassemble carefully to see if the guide rod stayed on the correct step or has moved.

Or I'm completely wrong.

I agree with Nuke. Looks like the guide rod is moving and rubbing.
