In general, heavy loads need heavy springs and lighter loads need lighter springs. There is no hard and fast rule as to how
much "Spring" a pistol needs. Too light a spring and the pistol opens and closes early and hard, increasing the felt
recoil and battering the frame. Too heavy a spring and the slide is hard to open and may not cycle completely, jamming the
