I have the 40c but think it applies to all SR's or probably any semi auto for that matter. At about what round count should I be thinking of replacing the spring on the SR series. I know that many manufacturers only rate their springs somewhere between 5000-8000 ish rounds before they suggest new ones. But I've never seen recommendations for the SR.
I'm about to start pushing 4000 soon.
