Couple of things you can try.
Wolff variable-power springs have a light section that makes it easier to get the slide started open, and a thicker part to prevent frame battering.

ISMI silicon springs seem a bit easier to open for the same overall weight of spring.

The spring has to be right for the load being used, so there is only so much leeway unless you handload. Easy way to check spring match is to see where the empties land relative to a standing shooter: about 3 to 6 feet away is optimum. Too heavy a recoil spring gives lazy ejection, and too light batters the frame. Unfortuately, the spring should match the load, not the shooter's comfort.
