The Wilson Combat Government 1911 .45 ACP 5-inch Match Barrel (brand part no. 33D) is a drop-in replacement barrel machined from aircraft-grade stainless steel forgings for full-size, Government-frame 1911 pistols. Wilson Combat heat-treats the barrel to Rockwell C 40 for maximum service life, then holds critical manufacturing tolerances to less than 0.0005 inch, roughly half a thousandth, for match-grade lockup and accuracy. Because it is a drop-in design, it installs without hand-fitting on a properly built Government-length 1911. For 1911 owners who want tighter tolerances and better accuracy than a factory barrel, this 1911 barrel is built to Wilson Combat’s match standard.
