M&P .357 Sig barrel in .40 M2.0??

[Doc Argyle]

Will a 4,25" bbl from an original M&P in .357 Sig fit the M2.0 .40 that comes with a 4.25" bbl?

Short answer YES!
I recently purchased a new FS M&P 2.0 in .40 and purchased the Storm Lake .357 Sig barrel. It dropped right in, no binding, tightness, sloppiness, reliable and accurate.
I also did the same research a couple weeks ago and was pleasantly pleased with the results. My research indicated that the barrels (1.0 and 2.0) are exactly the same.
