Let’s Talk About Evolution Gun Works Oversized Firing Pin Stop Series 70
The 1911 is a timeless design, and like many firearms, incremental improvements can significantly enhance its performance. One such improvement is the Evolution Gun Works Oversized Firing Pin Stop Series 70 (EGW FPS). EGW, a name synonymous with quality gun parts, offers this drop-in-ish upgrade to address common issues with the 1911 platform.
My Springfield Armory RO Champion, though a fine pistol, exhibited a slight extractor clocking issue and felt a bit snappy in the recoil department. I had read that a properly fitted, square-bottom firing pin stop could tame recoil and prevent the extractor from rotating, leading me down the path to the EGW Oversized Firing Pin Stop. The EGW FPS promises a tighter fit, improved ejection reliability, and potentially better recoil management.
Upon receiving the EGW Firing Pin Stop, I immediately noted its robust construction. The steel felt dense and well-machined, a stark contrast to the MIM (Metal Injection Molded) factory part it was slated to replace. Compared to a Wilson Combat firing pin stop I considered, the EGW appeared slightly more oversized, suggesting a more involved fitting process, but potentially a superior final fit.
My initial impression was excitement mixed with a touch of apprehension; the fitting process seemed daunting, but the potential benefits made it worthwhile. The promise of improved reliability and reduced recoil, all for around $15, felt like a worthwhile gamble for my beloved 1911.
Real-World Testing: Putting Evolution Gun Works Oversized Firing Pin Stop Series 70 to the Test
First Use Experience
The initial testing phase involved multiple trips to my local shooting range. I primarily tested the EGW FPS with 230-grain FMJ rounds, the standard for .45 ACP. The most noticeable difference was how the slide felt during cycling; it was smoother and slightly slower, indicating the square bottom was indeed slowing the slide’s opening, as intended.
Under dry conditions, the EGW Firing Pin Stop performed flawlessly, with consistent ejection and no signs of extractor clocking. I did not have the opportunity to test in extremely wet or dusty environments during the initial range sessions. After the first magazine, it was clear the pistol was running smoother, ejecting casings with more authority, and recoil seemed milder.
Fitting the EGW FPS required patience and a good file; it was NOT a drop-in part for my particular 1911, and required careful removal of material to achieve a proper fit.
Extended Use & Reliability
After several months and hundreds of rounds, the Evolution Gun Works Oversized Firing Pin Stop continues to perform admirably. There are no visible signs of wear on the FPS itself. The extractor remains firmly in place.
Cleaning is straightforward; a quick wipe-down with gun solvent is all that’s needed. Compared to my previous experiences with the stock firing pin stop, the EGW feels significantly more robust and reliable, providing consistent performance and peace of mind. The reduction in felt recoil, while subtle, contributes to a more comfortable and controlled shooting experience.
Breaking Down the Features of Evolution Gun Works Oversized Firing Pin Stop Series 70
Specifications
- Wider than normal design: This prevents extractor turning and promotes more reliable ejection. The wider profile ensures a snug fit, minimizing movement and ensuring proper alignment of the extractor.
- Thicker construction: Eliminates lateral movement and enhances durability. The increased thickness adds rigidity to the system, reducing stress on the extractor and increasing the lifespan of the part.
- Radiused inside corners: Prevents cracking and extends the part’s lifespan. The radius helps distribute stress evenly, preventing stress concentrations that can lead to cracks over time.
- .015 radius on the back corner: Breaks the corner while maintaining a square edge to slow slide opening. This subtle design feature influences recoil impulse and cycling speed, contributing to a more controlled shooting experience.
- Rockwell tested at 48 Rc scale: Demonstrates the part’s hardness and resistance to wear. This ensures the FPS can withstand the repetitive stresses of firing without deforming or failing.
- Available for all 1911 models, with caliber and series specific options: Guarantees compatibility with a wide range of 1911 platforms. This allows shooters to choose the FPS that best fits their specific model and caliber.
- Oversized Design: Requires professional gunsmithing or advanced user fitting. This ensures a precise fit for optimal performance.
Performance & Functionality
The Evolution Gun Works Oversized Firing Pin Stop Series 70 markedly improves the reliability and shooting experience of a 1911. Its primary function – preventing extractor clocking and improving ejection – is executed flawlessly. The slight reduction in felt recoil is an added bonus.
The EGW FPS is not a drop-in part and requires careful fitting by someone experienced with 1911s, or a qualified gunsmith. This is both a strength and a weakness; while the fitting process can be challenging, the resulting custom fit provides a level of performance unattainable with drop-in parts.
Design & Ergonomics
The EGW Oversized Firing Pin Stop is constructed from high-quality steel, reflecting the EGW’s commitment to durability and performance. Its robust build inspires confidence. While not directly ergonomic, the resulting smoothness in slide cycling and recoil management contribute to a more comfortable shooting experience.
The installation process requires some skill and patience but is manageable with the right tools and guidance. However, the square bottom design and oversized dimensions require precise fitting for optimal functionality.
Durability & Maintenance
Given its high-quality steel construction and thoughtful design features like radiused corners, the EGW Oversized Firing Pin Stop is built to last. Routine cleaning alongside standard firearm maintenance is all that’s required to keep it functioning optimally for years to come.
The robust build quality suggests it will outlast most factory parts and provide reliable service under heavy use. The design makes disassembly and cleaning relatively simple, further contributing to its longevity.
Accessories and Customization Options
The Evolution Gun Works Oversized Firing Pin Stop Series 70 does not come with any additional accessories, as it is a standalone component designed to enhance the existing 1911 platform. Its primary customization lies in the fitting process itself, allowing for a tailored fit that optimizes performance for each individual firearm. It works well with aftermarket extractors and recoil springs.
