I don't know if this will help but I have a C100 40 S&W and a PCR. The 40 S&W C100 has a wider slide at muzzle than the 9mm does. I bought a Vedder Pro Draw paddle holster for CZ P-01 to carry the C100. Nobody makes a holster specifically for a C100 40. It works after tightening the heck out of it. The pistol won't fall out but it's not really what I'd call tight.
On the other hand, after reading your post, I tried the PCR in it for the first time. It fit but really tight but not so tight I wouldn't carry it like that. Funny thing though the C100 frame is supposed to be a little bigger than the PCR.
Like you, I posted here asking similar question, got no response so I finally called Cajun Gun Works, (they know everything, don't they?) and one of the guys suggested Vedder. It worked for my C100.
BTW, my C100 is almost as heavy as my 75B 40 S&W. Figure that!
