Pookee:
Someone else will have to tell you about a leather holster for the E2e. Surefire has several leather holsters for other models.
The best E2e holster I have found is a Nylon Ripoffs model CO-124, available from
www.brightguy.com The holster is listed on the website as for the Inova X5 flashlight and others including the E2e.
This holster will accept an E2e with the standard bezel, or the KL-1 led bezel.You do not have to remove any clips from the E2e to use this holster.
The holster is two layers of black Nylon with a padding between the layers. A Velcro flap retains the flashlight It has a spring clip on the back that slides onto a belt up to 2-1/4 inches wide.The price is $13.25
Surefire also has a black Nylon holster which attaches with a belt loop. It has a Velcro flap to retain the flashlight. It will not however, accept the E2e with the KL-1 led bezel as the flashlight will be too long for the flap to close.
I hope this helps.
