The Wilson Combat Full-Size Reverse Plug for Bull Barrels (Wilson Combat part no. 585) is built for full-size Government-frame 1911s fitted with a bushingless bull barrel. Wilson Combat is one of the most respected names in match-grade 1911 pistolsmithing, and a bull barrel fits directly against the slide without a separate barrel bushing, so the reverse plug design takes over the job of capping the recoil spring at the muzzle end while working around the wider barrel diameter.

Key Specifications

• Sized for the Government frame, the full-size 5-inch-barrel 1911 platform.
• Built specifically for bull barrels, which fit the slide directly without a separate barrel bushing.
• As a reverse plug, it caps the recoil spring at the muzzle end while clearing the bull barrel’s wider diameter.
• It is not interchangeable with a standard bushing-style recoil spring plug, since bull barrel geometry differs from a bushing setup.
• It is sized specifically for full-size Government-frame pistols running a bushingless setup.
