If you have issues with the new guys first post asking for help, then be warned that is what I am doing.
I have a Series 70 (K014XXX) Custom Royal that was my daily carry until yesterday. While shooting a qualification course this weekend I started having more and more failure to feeds. The round is not coming up the feed ramp and the is not going under the extractor. Some times a mag tap fixes it, other times I have to rack and tap, and other times I have to drop the mag entirely. By the end of the course I was the god of malfunction clearance.
I took the gun home the first night and totally stripped it. Feed ramp looks great, the extractor was radiused and held a round properly, and the gun had absolutely no indication of any problem. It is un modified and had been totally dependable until now.
