this sounds like a ND. Keep finger off trigger while racking slide.

3.Keep your finger off the trigger until your sights are on target (and you have made the decision to shoot).
4.Be sure of your target and what is beyond it.
As far as how hard it is to rack, it gets easier with use. Racking the slide is not about strength.
It is all about technique.
