All mag tailcaps need to be cranked tight to make solid contact, the good thing is that allows the tailcap to lockout which is a must with high power lights.
The spring could also be trimmed a bit as it is fully compressed once the cap is on, I was going to trip mine also.
For the battery holder, mine moves in/out freely, it is a tight fit but has never stuck, nothing a little sandpaper won't solve! It would be good to notch the edge so a pair of needlenose pliers could grab it to pull it out if need be. Also drilling some holes through the solid areas between the battery cutouts would help lighten it slightly but I don't find the host heavy at all compared to my copper 26650 that is like a hand weight!
Thanks, I missed that. I don't have time or the funds to surf CPF like in the past. I spend all my free time on CPFM and some Ecig forums. Those guys use a lot of AW cells! I heard about this thanks to my Subscriptions and email.
