How do I change the tail cap boot on a Nitecore SRT3?

[pyro0]

My light came with an extra boot, so I am assuming it can be changed by the user. I would actually like to change the stock boot to a decent glow in the dark one (can anyone suggest one?) I'm supposed to stick like pliers into 2 holes near the spring and unscrew a plate, but I'm not seeing 2 holes, just multiple tiny pin hole sized holes around the spring. I'm not sure what to do at this point.

Secondly, is it possible to change the sensitivity on the switch? I'm used to momentary switches where I just gently press and then boom, lights on and off with ease and speed. I know there is a delay with light activation on the SRT3, but I was wondering if I could at least get it to switch on easier. Maybe swap or modify the original spring?

It's well sealed but you can send the service an email to ask for instruction.

Apparently, you're supposed to unscrew the metal ring from outside the tail cap, and not from the inside, like other flashlights.
