When I was in uniform and carrying "in public" I tried a number of holsters. They all worked pretty well but my favorite ended up being the Bianchi 5BL (different belt loop than the 5BHL). The 5BHL holds your gun slightly higher on the belt and, for4 me, put the center of gravity a little too high (but certainly still acceptable). These are "high ride" holsters.
I favor eBay for finding older holsters. The 5B/5BL have to be chased on eBay, not many appear. But the 5BH/5BHL are still in production and appear frequently on eBay. They work best on a 2 1/4" belt (the 1 3/4" belt loops hold the holster way too high). I wear five "keepers" on my belt, one keeper directly in front on the holster to prevent it being pushed forward while getting into and out of a car.
You might take a look at Tex Shoemaker leather. They offer a thumb break (TB) holster. It is pretty conventional as high-ride thumb-breaks go but Shoemaker will make it to whatever specs you supply for a very reasonable price. I use a 1 3/4" border patrol belt for carrying and they have custom-made several accessory pieces for me without complaining about my peculiar specs (e.g. I like to have 1 7/8" belt slots, try asking for that from the mega-leather companies).
