Hey guys wondering if anyone has seen or had anything like this before. Gun has low estimate of 20k rounds on it. Speer lawman 165 grain mostly. Glock 22 gen 4. Gun started to see Jams recently and then quickly turned into a jam o matic. Replaced everything chasing the issue, and saw this inspecting the frame. New frame with same magazines and slide and 1k flawless rounds. Not looking for a Glock vs xyz debate, I’m very happy with glock. Just looking to see if anyone else has had this experience and gain some knowledge here. Thanks guys
