OK - thanks!
Shit... I didn't know there were 3 different switch assemblies.
"Got the old one, need the new one... ooohh ooohh shiny thing for the gun!" isn't good enough?
Sorry about that, when I bought the light there were no options for switches. There was no discussion about what weapon or switch so I thought the x200 was universal. I just asked for a Surefire x200, got one, put it on the gun, good to go.
If you try to buy an x200B on the web it says "Accepts optional pressure-activated switch that extends under trigger guard." No mention of the switch or weapon type and no option to buy one.
Damn it... If anyone is looking for the same info, look here first. I snipped this from a .pdf of a newer catalog with the info:
