I had a sccy barrel from a mixed lot of parts so I edited the retainers and shored it up with a 3d pen rather than buy a glock barrel. It's been okay so far but I enjoy building more than shooting so I don't have many rounds through it, it probably will overheat the bushings now that you mention it. Maybe I'll print some with asa. The channel was easy, I made a 1.5 inch and the bit did wander in the threads but a round needle file got it opened up enough. Did you drill through the channel from the front when it was assembled? Some of the plastics from the threads got pushed in screwing in the bolt and it needed to be cleaned out.
