CS40 and CS45 in CQC Holsters

[cabindriver]

Will the CS40 and/or CS45 fit in a Blackhawk CQC Serpa holster? Even though Blackhawk told me they do not, the profiles seem so close to the 4000 and 5900 series pistols for which they do make holsters. Thanks.

I think the slides are too thick to fit in the Serpa in question.
