Let’s Talk About Evolution Gun Works Firing Pin Spring ISMI Premium
The Evolution Gun Works Firing Pin Spring ISMI Premium is a seemingly small, yet vital component in any firearm’s firing mechanism. Made by Evolution Gun Works (EGW), this spring promises enhanced reliability and consistency. Let’s delve into whether this affordable upgrade lives up to its claims of improved performance.
I’ve always been a stickler for reliability, especially in firearms. After experiencing some light primer strikes with a custom 1911 build, I started looking for ways to boost the firing pin’s consistency. This led me to the EGW Firing Pin Spring.
Upon receiving the spring, I was immediately impressed by its robust appearance. The spring felt noticeably sturdier than the factory spring it would be replacing. The black finish looked clean and professional.
I considered options from Wolff Gunsprings and Cylinder & Slide, both reputable manufacturers. Ultimately, the EGW Firing Pin Spring’s competitive price and specific focus on extra power for reliable primer ignition swayed me. My initial excitement was tempered by the knowledge that proper installation is crucial for any gun part.
Real-World Testing: Putting Evolution Gun Works Firing Pin Spring ISMI Premium to the Test
First Use Experience
My first test involved a trip to the local shooting range with my 1911. I fired approximately 200 rounds of various ammunition types, including some notoriously hard-priming surplus ammo. The weather was mild and dry, providing ideal testing conditions.
Right away, the difference was noticeable. Primer strikes were consistently deeper and more pronounced compared to before. There were zero light strikes, even with the surplus ammunition.
Installation was straightforward, but a minor adjustment period was expected with any new component. After a few magazines, the firearm cycled smoothly, and the trigger pull felt crisp and predictable. I had no initial issues or surprises.
Extended Use & Reliability
After several months of regular use, the EGW Firing Pin Spring continues to perform flawlessly. It has now seen over 1000 rounds, and the firing pin strikes remain strong and consistent. There are no signs of wear or degradation.
Cleaning is as simple as wiping down the spring with a lightly oiled cloth during routine firearm maintenance. I’ve noticed no change in its spring rate or performance after repeated disassembly and cleaning. Compared to my previous experiences with standard factory springs, the EGW spring shows a clear improvement in longevity and consistent power.
