I don't have one of their holsters (yet) but I have read very good reviews about their holsters for other guns. It looks like they have two holster options for the PPQ. I am actually planning on getting one for my P229 and M&P Shield a little later this year.
If you have questions e mail them; I have gotten very helpful and nice e mails back in less than a day both times I have asked them questions about their product.
PS: You can read a great review here
