The phrase "wanted dead or alive mare's leg" evokes a specific image within the world of firearms and Western lore. While sounding like a line from a classic poster, this term refers to a specific configuration of a Colt Single Action Army revolver, modified to fire from the shoulder like a rifle. This distinct setup blends the power of a revolver with the stability of a long gun, creating a tool historically associated with specific frontiersmen and practical needs on the range.
The Origin of the Mare's Leg
The name "mare's leg" originates from the physical dimensions of the firearm. To create this configuration, artisans shorten the barrel and modify the hammer and loading lever of a standard Colt SAA. This results in a weapon with an overall length similar to that of a rifle's stock, specifically designed to be braced against the shoulder. The shortened barrel and unique mechanics required a large loop on the loading lever, which, when viewed in profile, was said to resemble the leg of a horse, hence the name. This modification was not merely aesthetic; it was a functional solution for users who desired the handling of a revolver with the accuracy provided by a stable shoulder mount.
Functionality and Mechanics
Functionally, a mare's leg operates differently than a standard revolver due to its linkage to the loading lever. Pulling the trigger rotates the hammer and simultaneously actuates the loading lever. This action indexes the cylinder to the next round and cocks the hammer, preparing the weapon for the subsequent shot. This mechanical linkage means the weapon must be cycled between shots, making it significantly slower than a standard revolver for rapid follow-up shots. However, this design provided frontiersmen with a weapon that could be accurately aimed down the sights while still retaining the stopping power of a .44 or .45 caliber cartridge, bridging the gap between pistol and rifle.
Historical Use and Context
Historically, the mare's leg found its niche among specific groups who valued its unique balance of portability and power. Cowboys and lawmen utilized these weapons when they required a more compact option than a rifle but needed more range and accuracy than a pocket pistol. The weapon was particularly useful in situations where a rider needed to manage a horse with one hand while keeping a defensive tool accessible with the other. Its appearance in later media, particularly in the television series "Wanted: Dead or Alive" starring Steve McQueen, cemented its place in popular consciousness, transforming a practical tool into an icon of rugged individualism.
Modern Reproduction and Collectibility
Today, original vintage mare's legs are highly sought-after collector's items, prized for their historical significance and craftsmanship. Due to their age and unique mechanics, finding a functional original can be difficult and expensive. Consequently, the modern market is filled with high-quality reproductions and new builds that capture the aesthetic and function of the historical design. These modern versions often utilize stronger steels and improved metallurgy, addressing the durability concerns of the originals. They are popular among shooters who enjoy historical reenactment and collectors who appreciate the intricate mechanics and storied past of the American West.
Performance Considerations and Use Today
Shooting a mare's leg requires an understanding of its specific handling characteristics. The weight distribution differs from a rifle, and the leverage created by the short barrel and shoulder loop demands a firm grip. While capable of remarkable accuracy for a revolver, the effective range is limited by the ballistics of the cartridges typically used, such as .44-40 Winchester or .45 Colt. In modern usage, these firearms are primarily used for recreational shooting, plinking, and historical demonstrations. They serve as a tangible link to a specific era of firearms development, offering a tactile connection to the ingenuity of frontier gunsmiths.
