The spring in the V2 seems to mostly be to bring the handle back together after a tamp. It's probably a lot stronger than it needs to be. I've had mine apart and see no way for it to create a calibrated tamp of any kind, nothing in there is going to click or do anything else. The inside of the V2 is pretty simple once you see it and primarily designed to move linearly at 90 degrees to the plane of the basket.
