    I took my 20.4 out for the first time to since getting a 22# RSA. After shooting I took the slide off to see how dirty it was to see if it needs cleaned. This is what I saw,

    That line between the slide rails on the frame.

    Since buying my G20 new this is its history.

    1. Clean barrel and lube slide rail grooves
    2. 100 rounds of UMC Rustington
    3. Install extended slide stop and minus connector
    4. 100 rounds of S&B (today)
    5. 100 rounds of S&B with the 22# RSA (today)

    During the first 20 rounds of S&B with the 22#RSA I did get a light strike. I stopped, cleared, put the round back in and it shot fine. No other malfunctions.

    Can we see a picture of the inside of the frame from the muzzle side? I need to see the two plastic tabs that are roughly aligned with the serial number plate.


    PS: Is one of the metal slide guides chipped or is that just the picture?

    Rockets has it right, we need to see the same picture from the other way (from the muzzle end), we have to see where the slide contacts the frame under heavy recoil.

    Sorry, posted too late.

    Closer up and better light (turn the flash on maybe). Likely none though, at least from this perspective.

    EDIT - I did the close up look and saw no frame contact at all. More light will be definitive I suspect.

    No, there is a piece of metal molded under the plastic at that point to reinforce it. No reason to worry, various molds will expose it or not, sometimes it is more visible, others not at all - keep on going. (You'll now have guys swearing that they have never seen it).

    Natural tendency for new Glock owners to look for tiny faults in the Glock...not realizing they are just part of the expected norm.

    Do you want a pic looking down as if the gun pointed at the camera?

    The last picture was perfect, just more light pointed right in front of the front slide lug. The plastic in front of the front slide lug is what gets slammed when battering is happening. It starts to mushroom out to the center.

    With more light I could be definitive, but with what you have now, I would say if you had any, it is minimal.

    I concur with everyone else. From what I can see all is good, here is a very bad case of battering, you want to look at these two areas (left and right side) for any impact. Keep in mind the pic is worst case, that firearm is likely toast. If you see any marks in these areas it's time to put it down and figure out what is causing it before it gets too bad. That said I really don't think you have any issue.

    I don't think so, but you reminded me that I need to do laundry!

    That curved line of exposed metal is the body of the front frame rail fixture. The front and rear frame rail tabs in Glocks are the "ends" of 2 U-shaped fixtures that are molded into each end of the frame (1 at each end of the frame).

    In the front of the frame there's quite often a bit of metal left exposed due to the way to plastic fills in during the brief molding process (down to a little over 70 seconds nowadays, we were told).

    The plastic over the bottom part of the U-shaped front frame rail fixture is very thin. In some guns it looks like a hairline curved "crack" in the plastic frame, and in other guns there's quite a bit of exposed, bare metal visible.

    I've seen older Glocks (late 80's) where virtually the whole upper (top) surface of the U-shaped steel fixture, in the bottom "curve" of the frame, hadn't been covered by plastic when the frame was made.

    Not caused by "battering".

    My 1985 glocks have the metal exposed there...

    The area where the slide impacts the frame looks like it has been kissed by the slide some, but absolutely nothing to worry about.

    Refer to the picture Rockets posted in the link, that is frame battering from being under spring and running hot loads.

    When you get this condition, along with lightening up in load or adding recoil spring weight, you want to exacto the mushroomed area so it doesn't jam the RSA.

    But nothing to see here for the OP

    Yet, WeeWilly.

    Next week I'm shooting 50 each of Underwoods 155, 165, 180, and 200 stuff.

    Should be fine. My heaviest use G20SF has a clear impression of the front of the slide in those two side tabs but never got worse. I have run some really hot 10mm loads through it, hotter than UW and it never has shown serious mushrooming like the one in Rockets picture. This gun has a 22lb RSA.

    Enjoy that beast.

    I don't see a single mark where battering would occur.

    I agree with your assessment.

    After shooting my 200 grain Underwoods, I had the same concern, but Willy helped set my mind at ease. I just wasn't sure what I was looking for either.
