The grip could be a bit more stable, possibly rubberized and the switch is somewhat stiff. That being said, this light is powerful, small, and tough as nails.
Have 3 of the T2s and love them. Can't beat the lighting capability. However, I find the compression switch difficult to activate with gloves and sometimes when holding a pistol. I have modified by gluing a small (1/8 in) rubber "nub" on the switches which makes them significantly easier to activate.
