Hey guys I just scored a M961 and I want to have a LED head for it. Surefire site only shows KM3 and the KM4 as options for the M961. Are those the only two Options out there right now?

It's seem like this light has a lot of lego capabilities but I'm not sure where to find any charts on what they are.

Could I turn the M961 (9V) into a M951 (6V) and run a KX4 head? or Malkoff M60?
