    My gen4 17 has a gouged or peened spot in the middle top part of the block. I have only put about 175 rounds through it so far. The peened area seems to have stoped. but now the plating on the whole top is flaking off, and gets all around the inside when shooting.
    Is this a major concern, or will glock call it "normal"? It has got me ticked though. :steamed:
    Thanks!

    Were the rounds fired of the +P or +P+ variety by any chance? Peening is common on the .40 (and .357 I think), but I haven't seen any posts on the G17 that I recall. Nobody seems to worry about it on the .40's, and it stops as you say. The flakes aren't going to hurt anything. Evidently caused by frame flexing.

    A search for "peened or peening" brings up lots of reading.

    Is top of the locking block totally chipped? Get your kid in here to take a pic.

    Yup, the whole top is flaking off. Only a few specs left of the plating.

    Yes its normal, directly above it on the slide you'll notice some wear too. Its on my VERY used G17 and my fairly new G32...

    I wouldnt be upset about it. Its only goes to a certain point then it just stops.

    There is an outside chance that you have a broken trigger pin. A quick frame takedown will tell you.

    Since it is a Gen4 with 3 pins, I assume you are talking about a broken locking block pin (top pin) -- not trigger pin???
