I made my ultimate C3 it's a stainless C3 XPG R5 3 mode low, medium, high with no flashies it pulls 1.09 amps on a 14500 Flame and 1.95 amps on a Duraloop on high.
I removed the pill from the stainless C-3, cleaned up the threads and installed the SA-2 strobe deleted XPG pill and it fits perfectly. I then tied a green tritium tube on it with fishing line and I have my version of the ultimate C-3.
Interestingly enough the bad connection the stock C3 had suffered from went away with the installation of the SA-2 pill.
Next install the old C-3 Q5 pill in the SA-2, it also fits perfectly and sell it.
