Low voltage battery sounds like the solution you need. Putting in a stronger spring will increase piston loading and accellerate piston death.
How many shots are you getting per piston?
Are they stripping in the same place? If the first teeth are dying first, I suspect there may be something wrong with the initial piston alignment. It may be starting a bit too far forward or rearwards so you get even heavier wear on the first few teeth.
