Let’s Talk About Evolution Gun Works Mainspring Housing GR4 and GR5
The Evolution Gun Works Mainspring Housing GR4 and GR5 represent a crucial upgrade for any serious 1911 enthusiast. Evolution Gun Works (EGW) is known for its precision machining and dedication to quality, and these mainspring housings are no exception. They promise enhanced durability and a smoother action, elevating the performance of your 1911.
I’ve always strived for peak performance from my 1911s, and the factory MIM (Metal Injection Molded) mainspring housing on one of my beloved pistols was starting to show wear. I needed a robust replacement that would not only withstand heavy use but also potentially improve the trigger pull. The EGW housings seemed like the perfect solution.
The Evolution Gun Works Mainspring Housing GR4 and GR5 arrived neatly packaged. My initial impression was one of solid construction; the steel felt dense and well-machined, inspiring confidence. The finish was clean and even, suggesting a high level of attention to detail.
I considered a few other options, including mainspring housings from Wilson Combat and Ed Brown. However, the reputation of EGW for tight tolerances and exceptional value swayed my decision. Plus, the positive online reviews specifically highlighting the drop-in fit of the GR4 and GR5 sealed the deal.
I was genuinely excited to install this upgrade. It promised to address a weakness in my 1911 and potentially unlock a new level of performance. The solid steel construction and promise of improved trigger feel left me optimistic.
Real-World Testing: Putting Evolution Gun Works Mainspring Housing GR4 and GR5 to the Test
First Use Experience
I first tested the Evolution Gun Works Mainspring Housing GR4 and GR5 at my local shooting range, after installing it on my Kimber 1911. The range provided a controlled environment to assess the immediate impact of the upgrade. I ran approximately 200 rounds through the pistol, focusing on trigger control and overall feel.
The weather was a bit humid, which can sometimes affect grip and trigger feel. However, the EGW housing did not seem to be negatively impacted by the conditions. The installation was smooth, and the fit was perfect, as expected.
The most noticeable difference was a subtly smoother trigger pull. While the Evolution Gun Works Mainspring Housing GR4 and GR5 isn’t a trigger job in itself, the more consistent pressure it applied to the sear seemed to refine the action. The pistol felt more solid and responsive in my hand.
Initially, I experienced no issues or surprises. The EGW housing performed exactly as advertised, providing a noticeable improvement in trigger feel and overall build quality.
Extended Use & Reliability
After several months of consistent use, the Evolution Gun Works Mainspring Housing GR4 and GR5 has proven to be an incredibly reliable upgrade. I’ve put several thousand rounds through my 1911 since installation. The housing continues to perform flawlessly.
The finish shows minimal signs of wear, even after repeated disassembly and cleaning. The steel construction has withstood the rigors of regular shooting and handling, inspiring confidence in its long-term durability. Regular cleaning and lubrication are all that’s required to maintain its performance.
Compared to the original MIM housing, the EGW is a significant improvement. The original housing felt less substantial and showed signs of wear much earlier. The Evolution Gun Works Mainspring Housing GR4 and GR5 has exceeded my expectations in terms of both performance and longevity.
