I came across one of these at a gun store today. It caught my eye as I am a fan of older guns and guns that are chambered for an unusual caliber. This particular gun was in really great shape and I did a little research tonight on the history of it. Many people, like myself, who love guns are also very interested in history. Here's a little of what I found.
The Police Positive Special was an iterative improvement of Colt's earlier Police Positive model, the only differences being a slightly lengthened cylinder and elongated and strengthened frame to allow the chambering of the longer, more powerful .32-20 Winchester and .38 Special cartridges. In the early 20th century the Colt Positive and Positive Special teamed with Colt's other admired model, the Official Police, to capture the lion's share of the law enforcement firearms market. Very popular with law enforcement officers due to its light weight, the Positive Special went through a number of series or “issues”. The first issue ran from introduction to 1927 and had the early 1900-era distinctive Colt black hard rubber grips. The second issue introduced wooden grips which were smooth in the early years, later giving way to a checkered style, also the smooth topstrap was replaced with a serrated one. The Third issue began in 1947, and the Fourth issue in 1977 introduced a Colt Python-style shrouded ejector-rod housing. Production of the Police Positive Special ended in 1995.
The .32-20 Winchester, also known as the .32 WCF, was the first small-game lever-action cartridge that Winchester produced. It was initially introduced as a blackpowder cartridge in 1882 for small-game, varmint hunting, and deer. Colt produced a single-action pistol chambered for this cartridge a few years later.
