I use it for about 2 month already, the last time I recoil it and try to check the ohm on my vamo it read 9.9 so I checked the center pin of trident and it seem to be push in and doesn't make a contact to mod, somehow I can't manage to screw it out. Does anyone know how to fix this problem? 
Picture will come later as now I'm at university.
