Picked up a Surefire tapeswitch awhile back and finally decided to try it with the Surefire M3T[9 volt w/turbohead].
 Problem[seemingly] is that the 'directions' BEGIN with feeding the tail back thru the threaded cap [button already removed]. Whereas it seems straightforward enough[just push out the original button], mine doesn't want to move!
 Do I just push harder or is the button held in somehow that they don't mention? Since even the little parts cost dearly from Surefire, I don't want to break anything being heavy handed.
 Appreciate any input/pointers from users. TIA,Ghost

If its never been removed, it'll be tight, but it'll push out.  You're not likely to break it.
