I use the Comp 2's and a 686 for IDPA (I think the 3's are gamer) and like them a lot. I have a Fist holster ( WWW.FIST-INC.COM ) for the 686 and also like it a lot because they made it up the way I wanted it! Check them out. I will also say that there are a lot of other good holster makers out there.
FWIW
