History:

MK III

1969 – 1982 In the late 1960s, Colt began to be concerned with a decline in its market share because of price increases brought about by the high labor costs inherent in its manufacturing processes. In response, an entirely new product line of revolvers dubbed the MK III series debuted in 1969. Intended to be the first major advancement of Colt’s designs since the beginning of the 20th century, the MK IIIs used a new ‘J’ frame and had no parts interchangeability with older models. The new revolvers were considered groundbreaking as they were the first modern revolver designs to employ a state of the art transfer-bar lockwork system. This lockwork was not only more sophisticated but inherently safer due to its superiority to the older hammer-blocking designs; the revolver could fire only if the trigger was deliberately pulled completely to the rear. It also vastly improved on the earlier design in durability and offered the advantage of employing sintered iron internal parts rather than expensive forged ones. The sintered parts also allowed for improved fabrication tolerances and could be given a special heat treatment resulting in a harder more wear resistant composition. Using these parts virtually eliminated hand fitting, significantly lowering labor costs associated with the assembly and manufacture of the MK III line. The springs used in the Mark III internals were also an improvement. Unlike the older flat style, they were coiled and made entirely of corrosion-resistant stainless steel.

The MK III series incorporated a number of models, several of which were updates of existing designs. Classic models included the venerable Colt Official Police chambered in .38 Special as the basic/entry-level offering and the Trooper in .357 Magnum. New members of the lineup included the Lawman, Metropolitan Police, and Border Patrol.

Trooper

The .357 Trooper was the premier offering of the new product line, featuring a heavy barrel with a solid top rib as well as a shroud which protected the ejection rod. For the first time, the Trooper was offered with an eight-inch barrel length, and as the top of the product line model, it boasted a target-grade hammer, target stocks, and adjustable sights. The finish was upgraded to the lustrous Royal Blue or Bright Nickel which had been typical on the .357 model, and an additional duller satin-nickel finish option, known as “Coltguard” was added. A new ammunition chambering option, the .22 Winchester Magnum Rimfire, also became available for the first time.
