Does anyone have both pistols, or a parts list, and can definitively share if the Recoil Spring Assembly is identical when comparing the M&P 2.0 4 inch model, and the M&P 2.0 3.6 inch model?

Looking at possibly getting the 2.0 in 4" and curious about compatibility of critical parts, already owning the 2.0 in 3.6"

Customer service is typically phenomenal at S&W, but I was on hold for a bit and decided this may be faster.
