Let’s Talk About Evolution Gun Works Recoil Spring, ISMI 1911
The Evolution Gun Works Recoil Spring, ISMI 1911 is a critical component for any 1911 platform enthusiast looking to optimize performance and reliability. Manufactured by Evolution Gun Works (EGW) and utilizing springs from ISMI, this recoil spring promises enhanced durability and consistent performance compared to standard factory springs. I was intrigued by the claims of improved energy dispersion and reduced sight movement, especially considering my background in tactical applications.
My journey towards seeking out this specific recoil spring was driven by a desire to tame the recoil on my aging Government Model 1911. Years of use had taken their toll, and the factory spring was no longer providing the consistent cycling and recoil management I needed for accuracy and rapid follow-up shots.
Unboxing, or rather, receiving the spring was uneventful, as it’s a small component. My initial impression was of a well-machined, robust spring; it felt noticeably sturdier than the worn-out factory spring I was replacing.
Compared to other aftermarket springs, I chose the EGW/ISMI offering because of the ISMI name’s reputation for quality, and EGW’s overall commitment to precision parts. I had considered Wilson Combat and Wolff Gunsprings, but the specific claims about the silicone chrome material and its high-temperature resistance piqued my interest.
I was cautiously optimistic; recoil springs are often overlooked, but their impact on a 1911’s performance can be significant. I hoped this spring would breathe new life into my trusty pistol, improving both its shootability and reliability.
Real-World Testing: Putting Evolution Gun Works Recoil Spring, ISMI 1911 to the Test
First Use Experience
My first test of the Evolution Gun Works Recoil Spring, ISMI 1911 was at my local shooting range, focusing on rapid target acquisition and follow-up shots. I wanted to see if the claims of reduced sight movement held true. The range offered a controlled environment to assess the spring’s impact on recoil and cycling.
The spring performed admirably even in the less-than-ideal, slightly dusty range conditions. The cycling felt smoother, and the muzzle flip was noticeably reduced compared to my old spring. I didn’t experience any failures to feed or eject, even with various ammunition types.
The spring was surprisingly easy to install and required no modifications to my 1911. After a few magazines, the difference was apparent; the pistol felt more controlled and predictable.
Extended Use & Reliability
After several months of regular use, including weekly range sessions and a weekend training course, the Evolution Gun Works Recoil Spring, ISMI 1911 has proven its worth. It continues to deliver consistent performance and shows no signs of weakening.
The spring has held up remarkably well; there’s no noticeable wear and tear despite hundreds of rounds fired. I clean and lubricate my 1911 after each range visit, including a light wipe-down of the recoil spring.
Compared to my previous experiences with standard factory springs, the EGW/ISMI spring is a clear winner. It has significantly improved the handling and reliability of my 1911, making it a more enjoyable and effective pistol to shoot.
