Hi All:
Does anyone know if the Grand Power P-40L 5" .40 S&W barrel will fit, or can be machined to fit, a Grand Power P-40L 10mm? Also, what are the recoil spring weights appropriate to those barrels?

I just don't know the answer to that. I suggest you send an email to Eagle Arms and ask them, they may know, or may be able to point you in the right direction.
