triple retention holsters with a light mounted on my HK USP?

I am going to be buying the Streamlight TLR-1 (no use for a laser and the surefire version is still to expensive) here soon and will need a new holster as well. I have been using the Uncle Mikes Pro-3 for the last eight years, 3 as a reserve and 5 as an armored car guard(not anymore), and like the holster but they don't make one for a weapon mounted light. Just curious as to what you guys may be using or have had experience with; both light and holsters. Safariland, Bianchi, ??????
