A Glimpse into the Past
From the annals of firearms history, a legend still resonates: the Colts Mk IV Series 70 .45. This isn’t just a pistol; it’s a symbol, a statement, a testament to the enduring appeal of classic American craftsmanship and the power of the .45 ACP cartridge. For collectors, enthusiasts, and those who simply appreciate a well-made firearm, the Series 70 holds a special place. This article will explore the depths of this iconic handgun, examining its history, design, performance, and the lasting legacy it has forged.
The story of the Colts Mk IV Series 70 .45 begins in the shadow of a much older legend: the Colt M1911, a pistol that served as the standard-issue sidearm for the United States military for over seven decades. The M1911’s rugged reliability and stopping power during the first and second world war, as well as various other conflicts, cemented its place in history.
Following World War II, Colt continued to refine and improve upon the original design. The demand for civilian versions of the iconic handgun was significant. The company needed a way to make its products more accessible to the public, and also improve upon the existing design to ensure the future of Colt. The “Series 70” designation marked a new era, specifically aimed at addressing concerns about accuracy and performance in the civilian market.
The creation of the Colts Mk IV Series 70 .45 was not merely an update; it was a response to evolving customer demands and an opportunity to showcase Colt’s commitment to innovation and quality. This model represented an effort to modernize the venerable 1911 platform without sacrificing the design principles that had made it so successful. The Series 70 was born of necessity, a desire to meet the market needs for a reliable and accurate pistol. It was more than just a new model; it was the re-imagining of a classic.
Unveiling the Design and Features
Examining a Colts Mk IV Series 70 .45 reveals a meticulously engineered handgun. The pistol’s classic lines and proportions are immediately recognizable, embodying the essence of the 1911 design. Its overall aesthetic is understated, suggesting a blend of function and elegance that has made it a favorite among firearm aficionados for generations.
The frame, often constructed from steel, provides the robust foundation upon which the entire pistol is built. Its weight contributes to the pistol’s ability to absorb recoil and maintain stability during rapid firing. The slide, crafted from high-grade steel, houses the mechanism that chambers a round, extracts the spent casing, and prepares the next round. The slide design and markings vary across different production runs, making some models particularly desirable to collectors. The slide is a masterpiece of engineering, designed to work flawlessly with the frame for optimal functionality.
The pistol grip is an integral part of the design, offering comfortable and secure handling. The grip’s shape and texture can significantly influence the shooter’s control and accuracy. Colt typically used wooden, or plastic grips. The grip also houses the magazine, a single-stack design that feeds the powerful .45 ACP rounds into the chamber. The magazine capacity is another key aspect of its design, offering a balance between firepower and ease of carry.
The sights are a crucial element in aiming and target acquisition. Standard sights found on the Series 70 are usually fixed, offering a clear and uncluttered sight picture. Simplicity, however, does not equate to inefficiency; these sights are effective at their intended purpose. The thumb safety is another vital safety feature, preventing the pistol from firing unless intentionally disengaged. The grip safety is another safety device, requiring the shooter to depress the grip to allow the firing mechanism to engage.
The Accuracy Advantage
One of the key innovations of the Colts Mk IV Series 70 .45 was the inclusion of the now famous collet barrel bushing. The collet barrel bushing was designed to ensure greater accuracy, improving upon the designs used in previous models. The collet barrel bushing is a spring-loaded device that firmly clamps down on the barrel, reducing play and enhancing shot-to-shot consistency.
This design feature was a major selling point and a crucial element in the enhanced accuracy of the Series 70. The enhanced accuracy allowed the shooter to have more control, and the pistol to more consistently deliver the powerful .45 ACP round. The implementation of the collet barrel bushing marked a significant improvement in accuracy over earlier 1911 models, making it a favored choice for target shooting and personal defense.
Evaluating Reliability and Handling
The Series 70 is often celebrated for its mechanical reliability. The robust design and quality materials contributed to its durability. The pistol’s design has stood the test of time and, with proper care and maintenance, will continue to provide reliable service for years to come. While no firearm is entirely immune to issues, the Colts Mk IV Series 70 .45 is known for its generally reliable operation.
The handling of the Colts Mk IV Series 70 .45 is a notable aspect of its design. The ergonomics of the pistol are such that it fits comfortably in most hands. The balance, weight, and grip angle contribute to a stable and controllable shooting experience. Its weight assists in mitigating recoil, allowing for faster follow-up shots and a more enjoyable shooting experience.
Maintenance and Care: A Step-by-Step Guide
The longevity of the Colts Mk IV Series 70 .45, like any firearm, depends on proper care. Regular cleaning and maintenance are essential to ensure reliable operation and preserve the pistol’s value.
Disassembly for cleaning begins with making sure the firearm is unloaded. After confirming the absence of a magazine, and clearing the chamber, the slide is retracted and locked back. The slide stop is then removed, and the slide is carefully slid forward and off the frame. Following this, the recoil spring and guide rod are removed, after which the barrel and bushing can be removed from the slide.
Cleaning should involve the proper use of cleaning solvents, brushes, and cloths. The bore of the barrel should be thoroughly cleaned to remove any residue. The frame, slide, and other components should also be cleaned, inspected, and lubricated. Lubrication is crucial to ensure smooth functioning and prevent wear.
The Aftermarket and Customization
The enduring popularity of the Colts Mk IV Series 70 .45 has resulted in a thriving aftermarket. A wide range of parts and accessories are available for customization. For those wishing to personalize their pistol, there are plenty of available options.
Popular upgrades include different grip styles and materials, enhanced sights, and custom trigger kits. Professional gunsmiths and customizers specialize in the 1911 platform, allowing for extensive modifications and the creation of a truly unique firearm.
Weighing the Pros and Cons
The Colts Mk IV Series 70 .45, like any firearm, has its advantages and disadvantages. Its reliability, accuracy, and timeless design are significant benefits. The historical importance adds to its appeal for collectors. A vast aftermarket support network and the availability of parts are huge positives, ensuring it can be kept in service for a long time.
Some potential drawbacks include the wear and tear associated with older models. The design, while proven, may require more diligent care and maintenance compared to some modern firearms.
