Choosing the Right Design for Peak Accuracy

At Evolution Gun Works (EGW), we are obsessed with precision.

A high-performance 1911 demands components that work in perfect harmony, and the barrel bushing is critical for achieving superior accuracy and reliability. A proper barrel-to-slide fit eliminates play and ensures a consistent lockup.

That's why we offer two distinct, American-made 1911 barrel bushing designs: the innovative EGW Angle Bore Bushing and the traditional Straight Bore Bushing. Understanding the key differences will help you select the ideal 1911 upgrade for your build.

The Straight Bore 1911 Barrel Bushing: The Gunsmith's Choice

The Straight Bore Bushing represents the time-honored, traditional approach to fitting a 1911 barrel. As the name implies, the internal bore is machined as a perfect, straight cylinder, parallel to the 1911 slide.

To achieve a true match-grade fit, this design requires careful hand-fitting by a skilled gunsmith. The goal is to create a tight tolerance between the barrel, bushing, and slide, maximizing mechanical accuracy. When fitted correctly, the result is an exceptionally precise lockup.

However, an improper fit can cause "barrel spring" or binding—forcing the barrel into a stressed, unnatural position upon lockup. This can negatively impact consistency and prevent the pistol from returning to battery smoothly.

Choose a Straight Bore Bushing if:

• You are a skilled 1911 gunsmith or are having one professionally install the part.
• You are performing a traditional, custom 1911 build and enjoy the process of meticulous hand-fitting.
• Your primary goal is achieving the tightest possible tolerances through expert gunsmithing.

The EGW Angle Bore 1911 Barrel Bushing: The Modern Accuracy Solution

The EGW Angle Bore Bushing is our innovative, engineering-driven solution to achieve a perfect barrel lock-up with greater efficiency. We pioneered this design to solve the inherent structural challenges of traditional straight bores.

The key is that we machine the bushing's bore with a precise angle. This angle perfectly matches the natural tilt of the 1911 barrel as it locks into battery within the slide. This intelligent design provides full, uniform contact along the top and bottom of the barrel at the muzzle, effectively eliminating the "barrel spring" that can compromise your accuracy.

The result is a self-centering action that allows the barrel to return to a natural, stress-free position shot after shot. This leads to enhanced mechanical consistency and a far more forgiving installation process.

Many customers find our Angle Bore design to be a near drop-in 1911 barrel bushing, requiring minimal to no fitting (after being custom bored to customer specifications) while still providing the tight lockup needed for improved performance.

Choose an EGW Angle Bore Bushing if:

• You are looking for a high-performance 1911 upgrade that significantly improves accuracy with less fitting.
• You are a DIY gun builder or enthusiast who wants a superior fit without extensive gunsmithing.
• You want to maximize your pistol's reliability and consistency with a modern, engineered solution.
• It is our recommended choice for most 1911 Government and Commander models due to its advanced design and ease of fitting.
