This is something I made ages ago .. I am thinking this is the style you are referring to but correct me if I am wrong.
I no longer make that style of IWB. I know it got really popular and so I made a few on request but I promised myself and you will read in all my ads that first .. "I make a secure and quality holster .. then I make them pretty"
I try out anything I make. I dont make mine fancy since they are just to test design and I decided for leather the wrap around style of holster is best for IWB. The mouth is far harder to crush on a fold over design with throat support than on a flat, pancake style design. I know lots of well regarded holster makers make them and more power to them but I dont like them, I dont believe it is the best design for all leather construction so I dont make them.
I did see a leather worker but cant remember the maker who does a hybrid so it is flat like the one pictured above but he designed it to have a wrap around top. Nice design and I have something similar but with my own touches in the works but until I finish stitching it up and trying it I wont make it for sale. I have been making the wrap around but with straps at the throat since about '95 and believe in the design. I can certainly do two straps on the wrap around at the throat but I dont think that is what you are looking for.
For info purposes ... here is a message I just received yesterday from a customer who bought my IWB for his shield with the offfset clip
"I really like how the offset clip let's me get a true 12 o'clock carry. Walking the dogs in the warm weather has never been so comfortable. I went back to the small auto in your holster since the revolver printed badly at 12:30-1:00"
The kydex body flat designs with clips on either side should work well and one of the site sponsors sells them. I believe "High Noon" has them
