i got an upgraded spring and r.r. kit because the stock spring being "light" allows to the slide to began to cycle that nano second earlier than a heavier spring, which holds the slide closed for a nano second more and allows more powder to push the bullet out at a little higher velocity (in theory). plus it actually seemed to soften the recoil a bit, not that a G20 was bad in the first place.
