The KL5 is still in development at SureFire.
The KL5 has not been released.
SureFire have not given a release date for the KL5.
SureFire have not given a price for the KL5.
I hope they release the KL5 head simultaneously with the C3/9P body. I have no need for the functionality of the M2 body and would not want to pay up for it. A KL5 on the C3, or better yet, a HA3 9P Defender would be just dandy.
