Wow, the stars must be aligned just right. I was just about to post an almost identical thread.
I too have an SR9c (great gun btw). I am 6'3" 200lbs. The only holster I have tried thus far was the exact same Blackhawk http://www.cheaperthandirt.com/product/2-BHB990234BK
that BlackDogBrewing posted. I found it quite uncomfortable and not really what I would call concealed at all.
Sorry I'm no help beyond that.
Anyone tried the Versacarry yet? http://www.versacarry.com/
