I just received my High Noon Bare Asset IWB holster for my Kahr CW45. Sweet!
Fits snugly, but holds the gun well. No concerns about it falling out, unless I start climbing fences or jumping over ditches, but it draws easily. Comfortable for casual carry (so far), and conceals well. Very nice workmanship, and it was cheap! (~$35 including shipping).
I'll follow up after I've worn it a while, but it looks to be the ideal holster for my purposes.
