Effects of a lighter spring:
Recoil is transferred to the shooter in a shorter duration of time because the slide is moving at a higher velocity. This is often perceived as less recoil and reduced muzzle flip. With a lighter spring the shooter also has less force to counteract, or you don’t have to work as hard. This usually reduces muzzle flip. Less force to counteract reduces the odds of producing a limp wrist style jam. A lighter spring will result is reduced muzzle dip when the slide closes keeping sights steadier and on target for a faster follow-up shot. Light springs are particularly helpful to smaller shooters like children, women or anyone else having trouble keeping their wrists locked.
Effects of a Heavier spring:
Recoil is transferred to the shooter over a longer duration of time due to lower slide velocities. Slower slides equal a longer recovery time for the shooter. The shooter does more work, as there is more force to counteract. This often causes and increase in muzzle flip. The chances of a limp wrist style jam are increased, as there is more force working to unlock your wrists. The chance of the slide short stroking and causing a feed jam is increased. Increased muzzle dip when the slide closes for a slower follow-up shot.
