hello.....if i add a extra power striker spring (6lb) to a m&p 2.0 9mm.....
will it damage the striker in the long run?
or put more wear on it? or stress? just want to know?

I think we already discussed this....

yes ...we talked about if it would work. and it does!
new question is will it put added stress or wear over long run....
regardless have extra FPs...but just asking on wear?
