I love my UCH and thigh holster i got from blade-tech. Granted, they are both for a 4", so the UCH would be much more comfortable for say, an SC model

I like how it retains the gun, it seems like there is a nubby inside that the trigger guard slides over in addition to using the screws to adjust the tention.
Their thigh holster is very comfortable to wear. The one i purchased has the retention strap and is molded for the 4" with a Streamlight M3 attached. I use it with my Surefire X200 and it fits nicely.
Thats awsome about your belt holster, how do you like the tek-lok attachment ? I grabbed a magazine holder from them with the tek-lok style attachement and i like it a lot.
I dig their belt holsters because it looks like you can order one style and the parts for the rest and just change them out as you need. for example, buy the DOH, then buy the parts for tek-lok and paddle, but use the same 'holster' part. I think that adds basically 3 very nice holsters for the price of one.
After all the draws from my blade-tech holsters i'm impressed that i haven't noticed any wear on the slide as a result. I drew 3 times from my xd-gear holster and it scratched the hell outta my gun. I sprayed it down with some silicon lube and it seems to have fixed the problem, but the blad-tech gear was ready to go right outta the UPS shipping box.
