Colt Police Positive

The Colt Police Positive was one of the most important American law-enforcement revolvers of the twentieth century, helping establish Colt’s reputation in the police market long before the rise of modern semi-automatic pistols. Introduced in 1907, the Police Positive became the foundation for several later Colt D-frame revolvers, including the famous Colt Detective Special.

Collectors today study Colt Police Positive revolvers for their historical police use, compact D-frame size, production variations, Positive Lock safety system, and connection to the broader evolution of Colt double-action revolvers. Early examples from the pre-war years remain especially desirable, although later production revolvers—including the short-lived Fourth Issue guns from 1977–1978—have developed their own collector following.

The Police Positive line served police officers, security guards, detectives, and civilian owners for decades. Its reputation for reliability, manageable size, and modern safety features helped Colt compete aggressively with Smith & Wesson and other revolver manufacturers during the early and middle decades of the twentieth century.

Understanding the production years, issue changes, grips, barrel configurations, and relationship to the Colt Detective Special helps collectors identify authentic examples and place individual revolvers within Colt’s broader D-frame family history.

Colt Police Positive Production Years

The Colt Police Positive remained in production across multiple generations from 1907 through 1978, with a brief revival during the mid-1990s. Because the revolver evolved over several decades, collectors often divide production into five major issue variations.

Earlier revolvers typically featured classic pre-war Colt polishing and hard-rubber grips, while later guns incorporated ramped sights, improved lockwork, shrouded ejector rods, and updated grip styles. Production-era changes can significantly affect collector interest and value.

Police Positive vs Detective Special

The Colt Detective Special evolved directly from the Police Positive platform and became one of the most recognizable concealed-carry revolvers ever produced. Both revolvers share Colt’s D-frame design, but the Detective Special used a shorter barrel and compact configuration intended for detectives, undercover officers, and plainclothes carry.

• Police Positive: Usually associated with uniformed police carry and longer barrel lengths.
• Detective Special: Compact concealment-oriented D-frame revolver.
• Shared lineage: Both revolvers descend from Colt’s early twentieth-century D-frame platform.
• Collector crossover: Many Colt collectors pursue both revolvers together.

Historical Police Use

During the early twentieth century, Colt Police Positive revolvers became common sidearms among police departments, railroad officers, guards, and private security personnel across the United States. The revolver’s Positive Lock safety system gave Colt an important marketing advantage during an era when revolver drop safety was becoming increasingly important.

By the 1920s and 1930s, Colt revolvers such as the Police Positive and Official Police dominated much of the American law-enforcement handgun market. Even after larger magnum revolvers appeared, the Police Positive remained popular because of its manageable size and practical handling characteristics.

The Positive Lock Safety

As I write this, I’m thinking of the internal hammer block safety Colt called the Positive Lock. The Positive Lock prevented an accidental discharge even if the hammer was struck or the pistol was dropped.

Colt’s Positive Lock safety functioned by preventing the firing pin from striking the primer unless the trigger was deliberately pulled. Intended to address deficiencies of earlier models such as the Single Action Army, it allowed the revolver to be safely carried with all six chambers loaded.

Five Issues of the Colt Police Positive Special

There are five issues or versions of the Colt Police Positive Special. For collectors, the issue helps narrow down features, grips, sights, and production context.

End of an Era

If you’ve read my blog, you know how irritated I get at sellers using unwarranted descriptions like “ultra rare,” but in this case I think “rare” can be used for a one-year production gun. I don’t have the inside scoop on Fourth Series sales numbers, but I plan to research and learn as much as I can. My gut tells me this model was not very popular by 1977.

This gun has the distinction of being only the second gun added to my collection without me even considering having a holster made for it. I just don’t see me ever carrying this gun. I was not actively seeking this model when I bought it; I was shopping for something else altogether. As I scrolled past it, I backed up because a bell was going off: “VIPER.”

Semi-Automatics Take the Lead

If you are still here reading about this old Police Positive, I have to assume that you are a true Colt lover. The Police Positive was very successful. Along with the Colt Official Police, it dominated the law enforcement firearms market in the early 1900s. But by the time this Fourth Issue was released in 1977, it was the end of an era.

American gangster Al Capone used a Police Positive: a nickel .38 with walnut grips and a 4-inch barrel, manufactured in 1929. In June 2011, a private collector sold it at Christie’s for $109,080.
