Pressure Switch for G2X?

Is there one out there that is solid/reliable, and just replaces the rear cap? Thanks.

Surefire makes the XM07. That will work for the G2.
I have no experience with it, so I can’t comment on it other then saying I have never had a problem with any of my Surefire stuff.

Thanks - ouch that’s pricey…

One of the mods/instructors on here used the pelican tape switches ($15 or so)… I believe he said they worked fine. I’m not too sure about longevity due to abuse/exposure, though.
