I just got a holster for my Ruger SR9C from the Holster Store. Formed for the specific gun. Might investigate if they make one for the S&W, bet they do. While fairly rigid, bet its more comfortable than any Kydex material can be.

I also got a DeSantis Nemesis pocket holster for the SR9C. Works GREAT! Doesn't "print" in the pockets of a pair of "cargo" shorts. Easy draw, don't need to dress around it or sinch up a belt to make for a smooth draw out of the IWB holsters I prefer. Don
