So, I was on Wolff Springs website looking at replacement magazine springs for a P226 and I see references to magazines with single profile magazine springs and magazines with double profile magazine springs. So I google what this meant and the search returns only pointed me back to Wolff's site. What do they mean by single or double profile springs?

And one more question.

I have both OEM 15 round 9mm mags and Mec Gar 18 round 9mm mags. Does anyone know if the Wolff Springs will work in both of these mags.

Contact these folks regarding magazine springs:

They will know for sure.
