I recently bought a Safariland 568-54-411 holster. Got it for my Kahr CW40 which is lightweight and relatively thin.
It is a paddle type, the part that holds the gun is leather. The great thing for me is that it is adjustable and works equally well for my 40 cal compact Baby Eagle which is heavier and thicker than the Kahr.
It seems to work well on all types of human frames also, I am about 6' and 225 lbs and the guys in the store are about my height but probably 50-60 lbs lighter and this is what they use.
About $60.
