My Glock 23 has this problem where it's ejecting the brass all scraped up and sometimes with a piece torn off. (I tried changing the recoil spring but that didn't help) It also was giving me light primer strikes, some of them high toward the edge of the primer. I called Glock and they said send it in, so I sent it to them a little over two weeks ago. The gun arrived back here on Thursday with nothing but a packing slip inside it saying "INSPECTED, UPGRADE, MEETS FACTORY SPECS, TESTED OK" no explanation of what was wrong with it or what parts they may have changed. There was also a plastic bag with three fired casings which were dented and scratched :001_huh: So I took it to the range today and after 200 rounds I'd had 4 or 5 light primer strikes and all the brass coming out of it was scraped up, just like before. In the last 20 rounds fired the slide failed to return to battery three times (this was not due to limp wristing, I was very careful about that!). I changed recoil springs and it did it again! That is not good. Somehow I don't think them boys in Smyrna fixed my gun. I had always heard awesome things about Glock's customer service. I'm going to call them and send the gun back again. Has anyone else ever had to send their gun back to Glock twice? At what point do they just replace your gun? With all the trouble I've had with this one Glock I don't even feel like it's a safe gun to shoot. Btw, I've shot lots of other Glocks with no problems whatsoever, I love them, but I got a bad one when I bought this one.
