GCali, check out rmholsters.com and scroll to the bottom to look at the light holsters. 15 plus shipping, and they're made of kydex. Fits my QIII just fine, should I choose to carry it that way. . .
Try forum member "Wong" <[email protected]>. A few months back he was selling very nice nylon holsters that are perfect for one cell light lights like Q3. Very good quality for $10 US shipped.
