Just wondering if the C3 addresses something not seen in another Surefire light. I know the C2 is pretty comparable to the M2, but the M3 does not run on the same bulbs as the C3. In fact, other than the 9P, I'm not seeing others that run on the P90 and P91. If one was to use a one cell extender on the M2 the P90 and can be used right? and is there anything else that the C3 offers?
