Need help with possible takedown pin problem?

I noticed that the take down pin closest to the trigger is loose in its hole in the upper and lower compared to he other pins which are tight with no rotation possible. Its loose enough that shaking the gun it makes a rattle sound and is very easy to push out but yet doesn't come out on its own just yet. The rattle is annoying. It doesn't matter which pin I put in that spot they all act the same. I put pipe thread tape on it and that stopped it but that's a crappy fix. Anyone else have a pin that does this? The upper and lower are solid though.

EDIT: Had a friend come up with a better hack to stop the wobble. He took a piece of heat shrink tubing the diameter of the pin and cut a sliver of it only about 1 or 2mm long and slide it on the pin to the endcap and it stops the wobble of the pin and doesn't rip over repeat use like the pipe tape.

I  have not heard of this problem. Since the hole sounds like it may be out of spec, KRISS USA should be able to take care of it if sent into them. Thanks for sharing the workaround too.
