This is not a problem and the factory setting will be easy. Just for P26R replace reflector and LEDs for TIR optics and shorten the tube. Tailcap is the same. P26R is written on the P25 tailcap. I have P26R and P25 and the flashlights are almost the same. The idea for Fitorch on the new model?

It’s amazing how small the DQG Tiny 26650 is. Just a few millimeters larger than Fitorch P25.
