Ian, most nylon holsters tend to make retrieval of the Scorpion very difficult, especially in a hurry. I carry my Streamlight Scorpion in a Bianchi Accumold Elite flashlight holster. It does a great job in retaining the Scorpion for secure carry while allowing easy access and retrieval.
While the flashlight in the pic is not a Scorpion, it illustrates how the light is carried. I like it because there is no flap or velcro to mess with and the flashlight does not flop around. They are available in various sizes to accomodate several lights such as the Surefire 6P, Streamlight Scorpion, Streamlight Stinger, XT, and Poly Stinger. You can find more info about them on Bianchi's site under Accesories: Accumold Elite Duty. Click
