See the following link. I am now 100% confident that this was the cause for my failure to feed issues.

Don't want to sound stupid, but what is a "SP" failure?

That's when the round gets flipped as it stripped from the magazine and ends up pointing up. In my case both SP's were trapped on the feed ramp by the slide. BTW, SP means Stove Pipe because in some cases they can end up sticking up out of the ejection port, looking a bit like a stove pipe.
