The pragmatist in me is using simple logic to assert that extra power mag springs were not necessary and are now somehow shooting the last round up out of the chamber before it even has a chance to cycle, which is really weird.

This is why I don't change any springs in semi autos myself. My main concern is reliability. I feel like as soon as you change springs around if you don't know what you're doing you've totally changed the function of the pistol and now you're working backwards trying to fix an issue that probably didn't exist with stock springs.

Have you tried switching everything back to stock springs to see if you can replicate the issue? That's step one to finding the issue. Eliminate everything you've changed one by one until you figure out which component is the culprit and then go from there.

Don't just throw new springs at it.
