The strength of G&G gears are some of the worst I've seen. Putting in a spring that shoot much more than 400 FPS will consistently strip the teeth on the spur and sector gears. The teeth on the stock plastic piston and bevel gear don't seem to get affected for some reason. So yeah, keep that stock piston.
