Using a Nano Sim topic

I just picked up a Moto X during the big sale they had but I want to switch from that to my G3, question is that while I have a nano to micro adapter coming, I was messing around and put the nano directly in the SIM holder and it couldn't be read.

I get that with the adapter, everything fits properly, but the contacts will still be in the same place even if I put the nano directly in there.

Has anyone tried this on the G3?
