Colt Police Positive-revolver in .32 Colt New Police with a 6" barrel. This is a right-handed model. 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.

Sporting Colt's standard hard rubber grips, it was offered with barrel lengths of 2.5 (available only in .32 caliber), 4, 5, and 6 inches, and was chambered for the .32 Long Colt (it would also accept the .32 Short Colt), .32 Colt New Police, and .38 Colt New Police cartridges. [1] [2] [3] [6] Checkered Walnut grips became standard after 1923.
Initially made only with a 6-inch (15 cm) barrel, a compact 4-inch (10 cm) came afterward. Between 1955 and 1994, a downsized 2.5-inch (6.4 cm) barrel version was introduced which still sported full-sized grips. Colt also produced a few short runs of revolvers with a 3-inch (7.6 cm) barrel known to collectors as "Combat Pythons." [27] [28]
The first variant, the Officer's Model Target appeared in 1904 as a Premium model more focused on sport shooting than on common use, it was produced in 7.94 mm (.32) and 9 mm (.38) calibers, with barrels whose lengths ranged from 4 in (101.6 mm) to 7.5 in (190.5 mm), with 6 in (152.4 mm) being the most common.
Fitz Special. John Henry Fitzgerald, an employee of Colt Firearms from 1918 to 1944, first came up with the Fitz Special snubnosed revolver concept around the mid-1920s, when he modified a .38 Special Colt Police Positive Special revolver, [5] by shortening the barrel to two inches (5.1 cm), shortening the ejector rod, bobbing the hammer spur, rounding the butt, and removing the front half of ...
The Model 19 was produced in blued carbon steel or nickel-plated steel with wood or rubber combat grips, an adjustable rear sight, full-target or semi-target hammer, serrated wide target trigger or combat-type trigger, and was available in 2.5" (3": Model 66—rare), 4", or 6-inch barrel lengths. The weights are 30.5 ounces, 36 ounces, and 39 ...
An increasing positive correlation will decrease the variance of the difference, converging to zero variance for perfectly correlated variables with the same variance. On the other hand, a negative correlation ( ρ A B → − 1 {\displaystyle \rho _{AB}\to -1} ) will further increase the variance of the difference, compared to the uncorrelated ...
When first introduced by Smith & Wesson in 1935, it was known as the Registered Magnum. [citation needed] The model was essentially a custom-order revolver.Barrel lengths could be had in 1 ⁄ 4 inch (6.4 mm) increments from 3 + 1 ⁄ 2 to 8 + 3 ⁄ 4 inches (8.9 to 22.2 cm) inches in length.
