I don't know how I missed this first time around! Thanks for the review...
My general sense is that Eagtac's quality is higher than Klarus's also (referring to the question above)... on top of which, Klarus, like many manufacturers, has no idea how tactical lights are used (witness they're newest version of the XT interface de-tacticalizing (yes, that's a word) what used to be an amazing interface, in their utter cluelessness), whereas I agree with cyberescudo that this is a pretty solid interface. I have heard stories about Eagtac's pin-based interface being interfered with more easily than other interfaces by things like dirt, something to watch out for.
What do you think of the feel of the switch, particularly momentary? I have some P and D series Eagtacs where the switch is such short through that, under pressure, momentary is not very usable ... just a little extra pressure clicks the light to constant on. Hoping the T series has a longer-throw switch where momentary is usable
