Frequently Asked Questions

What modifications were made to the Springfield 1911 barrel and bushing?

The Springfield 1911 Government model featured a custom blocked and crowned barrel with a 40-degree radius. The barrel bushing was also 'melted,' meaning its sharp edges were rounded off for a snag-free finish and improved aesthetics.

What is the purpose of a 'melted' barrel bushing?

A 'melted' barrel bushing has its sharp edges rounded or smoothed. This modification primarily serves to prevent snagging on clothing or holsters, making it ideal for concealed carry pistols and also contributes to a cleaner, more streamlined appearance.

How does a custom barrel crown differ from a factory one?

Factory barrel crowns often have sharp 90-degree edges and visible tooling marks. Custom crowning, like the 40-degree radius shown, creates a smooth, beveled edge that protects the rifling and can contribute to better shot consistency.

What benefits does polishing the barrel and barrel hood offer?

Polishing the barrel and barrel hood results in a mirror-like finish, enhancing the pistol's visual appeal. Functionally, it can contribute to a smoother cycling action by reducing friction between these critical components.
