You may want to try either a gunshop or law enforcement supply house. Look for holsters made for police by Bianchi or similar. The ones made for the Streamlight Stinger usually fit the 8xx series Surefire. That or Ripoffs.com. The Ripoff holsters have a steel clip so you can use them without a belt. The nice thing about the police holsters is that they usually are hard sided - not soft nylon but nylon molded around hard plastic. Protects the light better.
