Evolution Gun Works 20 LPI Mainspring Housing SS Review

First Impressions of Evolution Gun Works 20 LPI Mainspring Housing SS

The 1911 platform is a timeless design, but its performance hinges on quality components. The Evolution Gun Works 20 LPI Mainspring Housing SS promises to be a robust and functional upgrade, something I’ve been searching for to enhance my own custom 1911 build. I’m eager to see if it lives up to the Evolution Gun Works reputation for precision and durability.

I was looking to replace the MIM (Metal Injection Molded) mainspring housing on my project 1911. MIM parts, while cost-effective for manufacturers, often lack the longevity and crispness of machined components. I needed a reliable, aesthetically pleasing, and functional upgrade.

Unboxing the Evolution Gun Works 20 LPI Mainspring Housing SS revealed a cleanly machined piece of stainless steel. The 20 LPI (lines per inch) checkering looked sharp and offered a promising tactile feel. The part felt solid and well-made, definitely an upgrade from the factory part.

I considered a few other options, namely Wilson Combat and Ed Brown mainspring housings. I chose Evolution Gun Works primarily because of their reputation for tight tolerances and excellent value. The price point combined with the promise of quality construction made it an easy decision.

My first impression of the Evolution Gun Works 20 LPI Mainspring Housing SS was one of cautious optimism. I was excited to see it installed and functioning but also aware that fit and finish can vary significantly. Only real-world testing would reveal its true worth.
