I am currently looking for a relatively inexpensive way to get lights mounted on more of my weapons. Particularly some of my HD shotguns. The Surefire G2 LED (http://www.surefire.com/G2-Led), says that the bulb assembly is virtually indestructible. Has anyone tried one out on a 12 gauge to see how it held up to the recoil with repeated use?
I guess this question also applies to 6P LED lights as they are slightly more expensive, but cost a lot less than a purpose made WML. There are also replacement tail-caps available so you can run a pressure switch from these lights.
