I thought I had this all figured out. I discovered the Z49 and decided to get a 6p, or better yet to me a 3P (should work right?) and attach. I want a small light I can turn on quickly with one hand. I still might do this but I was surprised to discover through this pic (down near the bottom of the page on the 9P) on Sean's site that the diameter of the Z49 is larger than the P body. I thought it would be the same.The form factor is not quite what I imagined. Still might look tough on that little 3P.
I also wish these were available for the E series. If so I would have one by now. My Scorpion is on it's way.
i think that the clickies for the "E" series should have been in the works along with the the "Z" tailcaps. galavanter,the Z49 will fit the 3P and i'm curious to see what it looks like.
