I don't think your problems have anything to do with mag springs, recoil springs, mags, or ammo. You had no problems for thousands of rounds, and now you've reached 10k and occasional problems have started. It's time for some maintenance.
First, I'll assume you have put in a VQ trigger. If you used the return spring VQ supplied, it has probably weakened enough to cause your reset problem. It's thinner than the Ruger spring and doesn't hold up well enough. Put the Ruger spring back in. If you're already using the Ruger spring, you may need to back the pretravel screw out about 1/4 turn. Also, if you're using a VQ disconnector, you may need to add a small shim to keep the front end held out against the right side of the frame. In my experience, all 3 of these things can/will cause reset glitches. Easy fixes though.
As for your feed/ejection problems, I think it's time for a new extractor. I know some people have claimed to use the original extractor for many years with no problem. But I find that all extractors wear out over time (at least in my pistols) and need replaced periodically.
Here's a pic of the first VQ extractor (on the right) I put in my MKIII after 13k rounds:
It was marginal by this time (like yours is now), and was worthless by 15k. I now pull my extractor out every 2k rounds, file off the galling, reinstall, and check for quality of function. It typically gets replaced every 10k rounds - just before function degrades to the the point of failures. Following this practice has prevented any feed/eject issues in my MKIII for nearly 30k rounds.
As a side note, I did have one VQ extractor's hook break off after only 3k rounds. They replaced it free of charge, but I now always carry a spare in my range bag. It sucks to have to leave the range early because a $10 part quit working.
BTW- the lines in the pic were showing severity and direction of the galling in an earlier post I made.
