Wilson Combat Match Grade Drop-In Barrel with Bushing 1911 Government .45 ACP, 1 in 16" Twist, 5" Stainless Steel

The Wilson Combat Match Grade Drop-In Barrel with Bushing is a precision replacement barrel for full-size 1911 Government models chambered in .45 ACP. Built on Wilson Combat's reputation for meticulous manufacturing, this 5-inch stainless steel barrel combines button-rifled construction with a matched bushing to deliver the accuracy gains serious shooters expect from a quality barrel upgrade. Whether you're refining a match pistol, building a duty gun, or restoring a worn-out 1911, this barrel gives you a forged component that handles the demands of centerfire pistol shooting without compromise.

The 1 in 16-inch twist rate is optimized for standard .45 ACP loads and bullet weights, ensuring consistent stabilization across common ammunition types. Button rifling produces a uniformly smooth bore with tight tolerances—a process that directly contributes to shot-to-shot consistency at distance. The included bushing is fitted to the barrel for improved slide-to-barrel lockup, a detail that separates match-grade parts from generic surplus components.

Installation of this barrel requires professional gunsmithing, particularly for proper bushing fitting and headspacing. Wilson Combat no longer installs the bushing at the factory, so plan to have a competent 1911 gunsmith handle the work. One important compatibility note: if your 1911 is a Colt Enhanced or Gold Cup model, the barrel hood will need to be narrowed during installation—discuss this with your gunsmith before ordering.

This is a core upgrade for anyone running a full-size Government-frame 1911 who wants measurable accuracy improvement and the longevity of a purpose-built replacement barrel. Pair it with quality ammunition and proper maintenance, and you'll get years of reliable performance.
