Over the years, I've replaced a dozen or so 1911 pistol barrels for various reasons. When military pistols were more common, wear and corrosion was a consideration. Later, the increased accuracy afforded by custom match-grade barrels from Bar Sto Precision was a leading factor. Today, some pistols come from the factory with match-grade barrels, but, of course, these are expensive high-end pistols. At the other end of the spectrum, service-grade pistols often come with a cost-cutting two-piece barrel. These pistols use a barrel that is brazed together, with one half meeting the other about at the chamber and barrel-lug line. While serviceable, these barrels are less than ideal.
