New myself. I just got my SD40VE but mine is 10 instead of 14. I have the same problem with mine..one rattles at 8 and the other rattles at 7. I just watched a YouTube video and I gentleman solved his issue by taking his clip and slowly and very carefullycrimping it in a vise till there was no more rattling. I'm going to try the same with mine as I don't want to be making noise CC. I will kept you updated with the results.
