I have been playing around with my arc 6 for some time and it is "the light" for me to EDC the only thing I have trouble with is the size of my hand and the size of the light. This keeps me from getting 100% satisfaction. Just on a whim I tryed a Piston from an EX10 and the button length greatly improved (to 100% level) my use of this light. but that piston does not fully fit the Arc6. Anyone have the contacts or ablity to build a mod piston that would be a cross between ARC6/McGizom piston and a EX10 piston( also the larger trit size would be a plus)
