    I got my Glock 20 slide back from having it milled for an optic. After assembling I noticed the slide was not flush with the frame. It seems to lock up and function properly. Any ideas?

    There's a typical variation with glocks in general. Here's my G20SF, with the slide sticking out past the frame. Everything is stock except the barrel. [​IMG]

    Is the recoil spring/guide rod in the correct notch on the barrel lug?

    Are you positive that it was flush prior to getting milled?

    Do you realize that’s a 10mm!!!! I could set off a nuclear warhead explosion that could end the world!!! or just go bang.....

    on a serious note, if the barrel is locked in it place and in the slide groves it should be fine.

    Can you take a picture of the slide lock?


    The slide lock has a lip along its top edge that should be facing to the rear of the gun. Having it flipped will cause what you're seeing.

    I tried reversing the slide lock and it didn't change. I'm positive it was flush before sending it out 20200630_170805.jpg

    Is your firing pin safety plunger moving up and down freely?

    If it had bushing, it could cover up all that "perfection" at the muzzle.

    Really though, I would completely strip down the slide assembly and reassemble. Could be a small bit of anything knocking it out of sorts. Worst bunch of malfunctions I ever had was when some pocket lint somehow got into my G20 firing pin channel.

    Have you tried it without the optics and the mounting plate installed. Maybe it was milled too deep and the screws are too lomg and are hitting inside the upper? Easy to try.

    I don’t think it’s worth fixing honestly. PM me and I’ll give you the address to send it to. My G29 would love the company.

    FC7E2E64-B5FD-488B-8718-9100DD4EC3AB.jpeg Just like Indie’s, my 20SF’s slide is a bit proud past the frame too. Shoots great, no issue with it here.
