FAQ

Is this a drop-in barrel, or will it require gunsmith fitting?
This barrel is machined to OEM specifications for a drop-in fit in the vast majority of M&P pistols. Minor fitting is sometimes needed for ultimate precision, but it should install and function reliably in-spec slides.

Does this barrel fit the M&P 2.0 Compact 4.0″ model?
No. This specific S&W barrel is designed for the full-size 4.25-inch slide platform. The Compact 4.0″ model uses a different barrel length and locking block geometry.
