Evolution Gun Works Drop-In Firing Pin Stop Series 70 Review

What You Should Know About the Evolution Gun Works Drop-In Firing Pin Stop Series 70

For those who appreciate the classic lines and proven functionality of a Series 70 Colt 1911 or its many variants, the Evolution Gun Works Drop-In Firing Pin Stop Series 70 represents a small but significant component that can contribute to reliable operation. As an experienced gear and equipment specialist, I’m always on the lookout for parts that promise a hassle-free upgrade or replacement, and this firing pin stop from Evolution Gun Works caught my eye precisely because of its “drop-in” claim. Specifically designed for GI .45 ACP government models, this component is crafted from blued carbon steel, aiming to integrate seamlessly without requiring custom fitting. My own quest for this part arose from a desire to refresh the internals of a well-used, vintage-style 1911, where slight wear on the original stop had become a subtle concern during intense range sessions. I considered a few other manufacturers, but the simplicity and straightforward description of this Evolution Gun Works offering stood out. My initial impression upon receiving it was one of understated quality – a solid, precisely machined piece that felt good in the hand.


Real-World Testing: Putting Evolution Gun Works Drop-In Firing Pin Stop Series 70 to the Test

First Use Experience

My testing primarily took place at my home workshop, where I carefully disassembled a Series 70-style .45 ACP pistol that has seen considerable mileage. The Evolution Gun Works Drop-In Firing Pin Stop Series 70 was installed during a routine cleaning and inspection. The installation itself was remarkably straightforward; it slid into place with no forcing or filing whatsoever, a testament to precise manufacturing for its intended platform. I then took the pistol to my local indoor range for a series of function tests, cycling the slide manually and then firing approximately 200 rounds of standard .45 ACP ammunition. The environment was controlled – a clean, dry range. There were no immediate issues or surprises; the slide functioned smoothly, and the trigger reset felt consistent throughout the session.

Extended Use & Reliability

Over the subsequent weeks, this particular firing pin stop has been part of my regular range rotation, seeing an additional 500 rounds through that same 1911. It has been exposed to typical workshop dust during cleaning and has endured fluctuations in temperature without any noticeable degradation. Crucially, there have been zero malfunctions directly attributable to this component; no light primer strikes, no failures to feed or eject, and no slide-related stoppages. The blued carbon steel finish, while not exposed to extreme conditions, shows no signs of premature wear or rust, even with routine handling and cleaning. Compared to a slightly worn factory part it replaced, this new stop has maintained a consistent performance level. Maintenance is as simple as it gets: a quick wipe-down with a cleaning cloth and a light application of gun oil during pistol cleaning.

Breaking Down the Features of Evolution Gun Works Drop-In Firing Pin Stop Series 70

Specifications

The Evolution Gun Works Drop-In Firing Pin Stop Series 70 is designed with simplicity and reliability as its core tenets. It’s constructed from blued carbon steel, a traditional material for firearm components that offers good durability and corrosion resistance when properly maintained. This model is specifically engineered for GI .45s and government models, ensuring compatibility with the established dimensions of these popular 1911 configurations. The key specification is its “drop-in” nature, meaning it is designed to require no fitting, a significant advantage for users who prefer or require straightforward part replacement. Its intended caliber is .45 ACP, and it comes in a black blued finish.

These specifications translate directly into user benefits. The blued carbon steel provides a robust internal component that can withstand the stresses of repeated cycling without deforming. The “drop-in” characteristic is paramount for DIY gunsmiths or those who simply want to avoid the cost and time associated with custom gunsmithing. For owners of classic or reproduction GI-style 1911s, this means a quick and effective way to restore or enhance their firearm’s function.

Performance & Functionality

The primary job of a firing pin stop is to control the rearward movement of the firing pin, preventing it from protruding too far forward and potentially causing issues, and also to help control the slide’s rearward travel. The Evolution Gun Works Drop-In Firing Pin Stop Series 70 performs this crucial role exceptionally well. During both manual cycling and live fire, its action was smooth and predictable. There were no instances of the firing pin hanging up, nor did it seem to impede the slide’s normal travel.

The main strength of this component lies in its precise fit and finish, which directly translates to reliable operation. It sits snugly in its recess without excessive play, ensuring consistent control over the firing pin. A minor point for consideration, though not a weakness, is that its performance is entirely dependent on the health of the surrounding 1911 components; it’s a part of a system, and while it performs its duty admirably, it cannot compensate for other worn or out-of-spec parts. Overall, it meets and exceeds expectations for a simple replacement part, offering dependable functionality at a very accessible price point.

Design & Ergonomics

The design of this firing pin stop is dictated by its function and the platform it serves. It’s a small, functional piece of metal, and its ergonomics are thus defined by how it integrates into the firearm. The blued carbon steel offers a utilitarian yet classic aesthetic that blends well with traditional 1911 finishes. The edges are clean and well-defined, with no sharp burrs or imperfections that could snag or cause discomfort during disassembly or reassembly.

In terms of usability, its primary design feature is the “drop-in” capability. This means the design is inherently user-friendly for anyone familiar with basic 1911 disassembly. There is no learning curve required; it is designed to simply fit. The finish provides a decent surface for handling, though it is a small part handled briefly during maintenance. Its sturdy construction instills confidence in its longevity.

Durability & Maintenance

From my experience, the Evolution Gun Works Drop-In Firing Pin Stop Series 70 is built to last under normal usage for a component of its type within a .45 ACP 1911. Blued carbon steel is a durable material, and provided it’s kept reasonably clean and lightly oiled, it should offer many years of reliable service. I have not observed any signs of premature wear, such as excessive peening or deformation, after hundreds of rounds.

Maintenance is exceptionally straightforward. It requires no specialized cleaning or care beyond what you would typically give to the internal components of your 1911. A quick wipe with a solvent-dampened cloth, followed by a light application of gun oil, is all that is needed to keep it protected and functioning optimally. I foresee no common failure points beyond potential neglect, like allowing rust to form on the carbon steel.

Accessories and Customization Options

This component, by its very nature, is a singular replacement part and does not typically come with accessories. Its primary function is to integrate into an existing firearm system. There are no direct customization options for the firing pin stop itself, as it is designed to be a specific size and shape for its intended application. However, its compatibility is with the standard dimensions of GI .45s and government models, meaning it works within the vast aftermarket ecosystem for these popular 1911 platforms. While you can’t customize the stop, the firearm it resides in certainly can be.
