Sorry about the tone, wasn't meant that way. I honestly don't think it's as difficult as it seems, but I've saved over the years a pretty long list of holster makers in my favorites.

Personally, from the above list I've bought holsters from Lobo, Winthrop, and TT (Tim Thurner). Of those three TT holsters are the cat's ass and I highly recommend him. Winthrop is a Cleveland area outfit that machine molds his leather holsters so they're not super detailed but they are made from quality leather and they do fit the pistol they're made for like a glove.
My daily carry (P-01) rides in either a TT OWB/IWB Convertible setup as IWB or in a Winthrop pancake for OWB. During the work day (since I need to leave it in the car) it goes into a simple Clinger kydex clip IWB holster so I can toss it in the glove box and then clip it on before getting out to do errands or whatever.
