Alessi. They take orders only by phone, handmake each holster to order, and are in (IIRC) New York.
I bought the exact same rig you are looking for, and am very happy.
Wide, comfortable and simple velcro leg strap, with a well-made holster, no safety strap, but a secure fit. The unit, when worn correctly, feels secure even when I jogged a bit (to test security, not for excercise.)
I'll see if I can find my paperwork/contact info.
IIRC, it was about $90.00 or so, took a few eeeks to get it.
Down side, I didn't realize until later that the rig didn't fit under some pants, like relaxed fit straight leg jeans. It is good concealment if it fits.
