Count me as an avid 9mm Shield owner. Had the same spring related racking/loading issues a lot of others have, but obligatory regular use has really tamed both mag and slide.

I did just buy a handful of ProMag aftermarket mags (I know, I know) for range use, and the danged springs are so wound up I resorted to ordering an UpLULA to save my thumbs and get that 8th round in.

I haven't taken the ProMags out yet, that might need another thread.....
