The Shadow Systems MR/XR Threaded Barrel, 4.5 Inch, Black (Shadow Systems part number SG9C-02-03TSPL-NIT) is a factory-spec replacement barrel built for Shadow Systems’ MR and XR series 9mm pistols. Shadow Systems machines minor improvements into every barrel for more consistent lockup without giving up reliability. The chamber is fully supported, so the barrel handles hot +P ammunition and lead bullets without the case-support concerns that come with a stock, unsupported chamber. Every sample barrel from this line survives 5 proof rounds during testing, so mainstream, commercially available ammunition is unlikely to cause issues. Finished in black, it is a solid upgrade or replacement option for MR/XR pistol owners who want a factory-matching look.
