I guess every distributor is going to have a former customer with an unresolved issue. CAI were cool when they had thier Canadian operation. As a kid I used to drool over thier catalog. Now it seems some of thier rebuilt rifles have trashed thier reputation.
I trust they will do right by customers buying the Grand Power guns. I know when STI were distributing the two models, any time STI had trouble keeping customers happy, the factory was dealing direct to make things right. Between STI and Grand Powers engineering team, they also discovered areas where the guns could be improved.
