Welcome to the forum Black Jaque Janaviac, the proper way to chamber the first round is to slingshot the slide. Insert the magazine the grasp the slide, pull it back and let go. Don't use the slide stop, and don't pull back and ride the slide until it closes. Pull back and let it go.I had the same problem. I sent it in. It doesn't seem to fail-to-feed, unless I rack the slide too gently while chambering the first round. During fire cycling it doesn't seem to fail though.
It makes me wonder if the nose of the bullet doesn't still get dinged, but just not severely enough to jam.
I don't think polishing the ramp will do much since the nose of the bullet hangs up on the very bottom edge of the ramp. This only seems to happen with the first round or two of a full magazine. After that the bullets quit nose-diving.
What causes the nose-dive? Why is there a big gap between the first two cartridges of a full mag?
