You can run a 20lb spring with standard pressure 40sw . The 2.0 40sw run a 18lb spring now . M&P pistols were know to be under sprung with the 1.0 models and one reason the 357sig cartridge had so many issues for LE that it was removed from the line up years ago , to many issues .

How about you assume what your new to you 40sw is just fine like it is and shot away . Or dabble away .
