Avoid the Fobus, at least the one that comes up for the CW9, on Amazon. I love them for a lot of my other guns, but there are different styles of the Fobus. The one I bought off of Amazon does not fit properly. I'll put the description from Amazon below (no link, though) so you can avoid it. I was actually going to review it on my web site, but since my whole thing is to give away the holster at the end of the review, I didn't want to give someone a crap holster. Here is the description of what NOT to buy for the CW9:
Fobus Roto Holster RH Belt C21BRB Browning HP Compact Style / Kahr CW9/ PM9/ P9/ T9/ MK9/ K9/ TP9/ T40/ K40/MK40/ PM40 / 1911 Style -All Models & Para C645 -Compact Style / FireStorm - Compact .9, .40, .45 cal / KEL-TEC PF9
