The KCI (Korean) mags have weaker/lighter springs and the internal mold flashing needs to be cut away and removed. If you take them apart and clean the flashing from the inside and spray them down with a good silicone lubricant... they work just fine. And you can also replace the springs with OEM Glock or Wolff springs and make them even better yet.
wait, did we have a discussion about this before? Because that is my exact method for making them reliable.
the wolff springs are really affordable for what they are and they are the heart of what a magazine needs to function when there are fewer rounds in the mag.
They generally function fine with that funky flashing, but if you're OCD, doesn't hurt to shave that joint with a razor
