The Colt MK IV Series 80 represents a significant chapter in the history of Colt's legendary 1911 pistols. This iteration, introduced as an improvement upon its predecessors, boasts a number of key features that cemented its place as a favorite among both collectors and shooters. This comprehensive guide delves into the details of the Colt MK IV Series 80, exploring its history, specifications, variations, and enduring appeal.
The Series 80's Defining Feature: The Firing Pin Block
The most significant difference between the Series 80 and earlier Colt 1911s is the inclusion of a firing pin block. This safety mechanism prevents the firing pin from striking the primer unless the trigger is fully depressed. This addition significantly enhanced the pistol's safety, addressing concerns about accidental discharges that had plagued earlier models. This made the Series 80 a more reliable and safer option for both law enforcement and civilian users.
Specifications and Variations: Understanding the Nuances
While the Series 80 is known for its firing pin block, several variations exist within the series. Understanding these variations is crucial for collectors and enthusiasts alike. Key aspects to consider include:
Caliber:
The Colt MK IV Series 80 was predominantly chambered in .45 ACP, but variations in 9mm and .38 Super also exist, though they are less common. These caliber differences often influence the pistol's weight, recoil characteristics, and overall balance.
Barrel Length:
Most commonly found with a 5-inch barrel, some variations include shorter barrels, impacting the pistol's maneuverability and concealability. Shorter barrels generally result in a reduction in velocity and accuracy at longer ranges.
Finish and Grips:
The Series 80 was offered with various finishes, including blued steel, stainless steel, and occasionally, nickel. Grips also varied, with plastic, wood, and even ivory options available depending on the year of manufacture and specific model. These aesthetic choices significantly impact the pistol's overall look and feel.
