The immediate fit felt substantial, a promising sign of the precision manufacturing.

The installation was straightforward, though it’s crucial to remember that this is not a drop-in part as the manufacturer explicitly states. It requires careful fitting, which is part of the charm and necessity of working with classic firearms. Once properly fitted, the pistol cycled with a noticeably smoother feel during dry cycling. At the range, the most significant impact was observed in the ejection pattern; spent casings were consistently and reliably sent further and more predictably away from the ejection port. Even after several hundred rounds, including a session where the pistol was exposed to a bit of workshop dust, the performance remained consistently excellent.

First Use Experience

My first hands-on experience with the Evolution Gun Works Oversized Firing Pin Stop Early Colt Service Model Ace / Early Colt Conversion Notched involved its installation. This part is not a simple swap; it necessitates precise fitting to achieve its intended benefits. I meticulously filed and stippled the part in my workshop, ensuring a perfect mating surface within the slide. This hands-on approach is typical for anyone who truly appreciates and maintains older firearms.

The initial live-fire test at the range was revealing. The most apparent change was the improved ejection of spent brass. Instead of sometimes fanning across my face or falling too close, casings were consistently thrown clear, a small but significant improvement in shooting comfort and safety. There were no malfunctions or failures to feed or eject during this initial session, which is exactly what you hope for when upgrading a critical component.

Extended Use & Reliability

After several months of periodic use, including range trips and the occasional dry-fire practice session, the EGW firing pin stop has proven its worth. The initial reliability it brought to my early Colt Service Model Ace has been sustained without any noticeable degradation. There are no signs of undue wear on the part itself or the surrounding slide components, which speaks to the quality of the Rockwell tested: 48 Rc scale steel.

Cleaning and maintenance remain as simple as any other part of the pistol’s disassembly. A light cleaning with a solvent and a touch of lubricant is all that’s needed to keep it in optimal condition. Compared to the original part it replaced, the enhanced stability and more positive interaction with the extractor and slide are evident. It has certainly outperformed any generic replacement parts I might have considered in the past.

Breaking Down the Features of Evolution Gun Works Oversized Firing Pin Stop Early Colt Service Model Ace / Early Colt Conversion Notched

The Evolution Gun Works Oversized Firing Pin Stop Early Colt Service Model Ace / Early Colt Conversion Notched is designed with a specific purpose in mind: to enhance the reliability and longevity of early Colt Service Model Ace and .22-45 Conversion units. Its construction and dimensions are tailored to address potential weak points in the original design, offering a tangible upgrade for discerning owners. The focus is on preventing issues before they arise, ensuring consistent performance with each cycle of the firearm.

Specifications

The specifications provided for this firing pin stop are key to understanding its functional advantages. It is made from hardened steel, Rockwell tested: 48 Rc scale, ensuring superior wear resistance and durability. The oversized nature of the part is its most prominent characteristic, meaning it is manufactured to be slightly larger than standard dimensions. This deliberate sizing is designed to prevent the extractor from turning excessively, a common cause of ejection issues in some firearms.

Furthermore, the firing pin stop is also thicker to eliminate lateral movement, contributing to a more stable and consistent operation of the firing pin mechanism. The inside corners are radiused to prevent cracking, a thoughtful design element that enhances the part’s lifespan, especially under the stresses of repeated firing. The back corner features a .015 radius to break the corner but maintains a square edge to slow the slide opening, a subtle but important engineering detail for controlled cycling.

Performance & Functionality

In terms of performance, the Evolution Gun Works Oversized Firing Pin Stop Early Colt Service Model Ace / Early Colt Conversion Notched delivers exactly what it promises. Its primary function is to ensure more reliable ejection by providing a more stable platform for the extractor. This is achieved through its wider dimensions, which limit the extractor’s ability to twist or shift during the extraction and ejection cycle.

The thicker profile also contributes to a more solid lock-up within the slide, reducing any potential for “slop” or play that could affect timing. The slight radius on the back corner is a masterstroke; it prevents the sharp corner from potentially snagging or causing excessive wear, while still providing enough resistance to manage the slide’s rearward travel for optimal timing. Its core job is to make the firearm run more consistently, and in this regard, it excels.

Design & Ergonomics

The design of this firing pin stop is purely functional, prioritizing robustness and precise interaction within the firearm’s slide. It’s crafted from high-quality steel, giving it a substantial and durable feel. The black finish is utilitarian and blends well with the internal components of a firearm.

While not a part directly manipulated by the shooter during operation, its ergonomic benefit comes indirectly through improved firearm function. A well-fitted and stable firing pin stop contributes to a smoother overall cycling of the slide. The attention to detail, such as the radiused inside corners and the specific radius on the back corner, demonstrates a deep understanding of the stresses and mechanics involved in a firearm’s operation.

Durability & Maintenance

Durability is a significant selling point for this EGW part. The use of hardened steel, tested to 48 Rc scale, indicates a high level of resistance to wear and deformation. This is crucial for a component that is subjected to the repeated impacts and stresses of firearm operation.

Maintenance is minimal, as is typical for internal firearm components. Regular cleaning and lubrication during routine firearm maintenance are sufficient to ensure its longevity. The robust construction suggests that this part is designed to outlast the original component in many cases, offering a long-term solution for owners of these classic Colt models. There are no apparent failure points beyond what would be expected from normal wear and tear on any firearm part.
