Kev1-1
SOEgear.com has the "E2" holster that is absolutely perfect for the E1e/KL1. O.D. or black nylon. Quick-release, adjustable belt loop, very strong velcro flap. These are the only holsters that I use to carry ALL of my Surefire lights. I emphasize the "E2" holster for the E1e/KL1 carry because of overall length and secure flap closure.
Hope this helps.
