hi, the pistol grip one is discontinued. I bought one about two years ago, and returned it twice for replacement because the battery would not charge.
the instructions seem to give the idea that you can leave it in the holder, so its fully charged when needed. bosch who deal with replacements say no, its not to
be left on charge all the time. the item is non-serviceable, and on the second replacement was sent the pen type one, which so far has been perfect.
