The ZORM Mount weighs about two-and-a-half ounces according to the published material and will hold any flashlight with a body diameter between .7 and 1.1". This is accomplished by the use of sizing adapters which are provided with the mount. Price point for the mount on the ElZetta website (linked below) is $65.95. As always, I recommend you search around and price shop.
All in all I was impressed with the light. It certainly took all I threw at it and kept on working with no issues. The mount is handy and easy to manage and isn't ElZetta product specific for use. I recommend you check them both out.
