While Lasermod what successful at the modification of his PGLIII, this laser is no Leadlight, and should not be handled as so. LaserMod is somewhat of a "modding god" on the forums and can modify just about any handheld laser I'm very sure. Not to say you are not capable of such work, but you might want to just be aware of the fact that a few people have posted failed attempts to mod/ have ruined this laser. IMO, if you want more power, pay for it (unless its something like a Leadlight).
Good luck with your decision.
