I have an older Sure Fire 9P (marked Laser Product Fountain Valley CA) I put a Malkoff P60 SHO in it and would like to put some type of click switch in it, but am getting comfused. Bought a Solarforce switch that work fine on my old 6P and a M-2, but doesn't seem to function on the 9P. Lots of different solarforces out there along with a z-57 Sure Fire some Ultrafires and MccGizmo McClicky. Which one will work? Not looking for anythingother than click on and click off, and the ability to set it on its tail would also be nice. So Solarforce, Z-57, Ultra Fire of Mc Clicky?
