Try checking the pill in the head and see if it’s loose. If so, tightening it up. If that’s secure, it could also be the tail switch is loose. Take off the o-ring that secures the tail cap. Then take the cap off. You’ll see the actual McClicky switch. See if that’s loose and if so tighten it up...
Probably best to contact them and get clarification. I'd imagine they would ask you to send back the light and they will put you on the list of people who requested to wait for the corrected version. Edit: nevermind. I just saw SNES's reply.
In a way, this halt on production is an opportunity for a collector. I doubt it would be on the same level as a Honus Wagner baseball card but the series of events leading to its rarity is similar. With that said, do we know if all four models of this mkiii has been released?
I'm interested in this but I can't commit just yet. I'd like to get come clarity about the sale. Are all of the lights in the posted pics included? Also, the description only mentions the mag light and MJ, but even then, the Mag light states a rotary control, which the pic does not reflect.
