So, how durable are McClicky switches when installed in Z41 tailcaps? I have a couple of surefires with malkoff drop ins which are wonderfully bulletproof which I would like to upgrade to a clicky but I don't want to introduce a weak spot, either. Interestingly I've found that even after cleaning occasionally these z41 switches do have a bit of poor contact and require a little wiggling, so I'm hoping the McClicky might actually improve reliability in that regard. Just mildly concerned about impacts on the switch itself, though I doubt it's really an issue...
