The Faxon Firearms 9mm threaded barrel (brand part no. M&PB910NSSOQ-T) is a straight-thread replacement barrel for the Smith & Wesson M&P Shield, measuring 3.7 inches and finished in black. Unlike a tapered thread barrel, this straight-thread design is built specifically for mounting a compensator or suppressor without needing a separate shim kit to index timing. It ships without sights, since most shooters adding a threaded barrel are also adding a red dot or suppressor-height sights as part of the same build. As a drop-in replacement for the factory Shield barrel, it installs the same way the original barrel comes out, no gunsmithing required.
