Ed Brown 4.25-Inch Threaded Commander Barrel, 1911 .45 ACP

The Ed Brown Commander Barrel (Ed Brown part no. 9243-45-SR) is a 4.25-inch drop-in barrel chambered in .45 ACP, built for Commander-length 1911 pistols and cut with muzzle threading so owners can add a compensator, thread protector, or suppressor-ready mount. Ed Brown machines its barrels to match factory 1911 dimensions, so this barrel installs as a drop-in fit rather than requiring custom fitting by a gunsmith. It is a straightforward way to add threaded-barrel versatility to a Commander-length 1911 without changing the pistol’s overall size or handling.
