FIST has been pretty good about covering an awful lot of guns with their Model 1K thin kydex. You might really like them because they don't fold over the kydex in making the holster they sew two pieces together (very thin kydex) and it makes for a very thin holster. They made one up for a 4" N frame for me that carries really well AIWB. (and they're only about $45-$50).
