Got mine from FIST, no problems. Great folks to deal with and reasonable price for what you get.

I have a couple with the loop sewn on, and a couple with belt clips. I wear the clip on ones "backwards" (OWB) so you must specify what direction you want it if you go this route. They say they're designed for IWB carry.
