I think that you are correct the double clip would be your best option and the carbon fiber is just for looks, it is the same material as the black with just a pattern on it. Thanks!

I'm thinking of trying an IWB for my G30. I know it would need double clips and I would like combat cut, but don't need belt slots. Is there an advantage to carbon fiber kydex and are there any design suggestions you would have for this weapon?
