Mare's leg rifle USA, 1892

The Mares Leg (aka Mares Laig; both sometimes spelled without the apostrophe) was the name given to a customized shortened rifle by Steve McQueens character on the television series Wanted: Dead or Alive (19581961). McQueens character was named Josh Randall, and the gun has also been referred to as a Winchester Randall, or a Randall Special.

The original Mares Leg was made by cutting down a .44-40 caliber Winchester Model 1892 rifle to a size that could be worn in a large leg holster and used with one hand. The barrel was cut down to a length of twelve (or possibly nine) inches, and much of the butt-stock was removed. For filming three guns were actually made, each with an enlarged loop on the cocking lever. The first gun differed in the size of its lever enlargement, and the last gun had an octagonal barrel instead of a round one. The actual gun being used could sometimes change from shot to shot in a given scene. While the guns were chambered for the .44-40 round, McQueen wore more impressive looking .45-70 rounds in the loops of his gun belt.
