Wanted: Dead or Alive was a half-hour Western television show which ran from 1958-1961. It starred Steve McQueen as the bounty hunter Josh Randall. The character was noted for wielding a modified Winchester 1892 .44-40 lever-action rifle called the "Mare's leg". With a reduced stock and a barrel cut down to less than a foot long, Randall could carry it holstered on his hip. It was his signature piece, and now gunmaker Rossi is selling it in .44 magnum, .45 Colt, and .38 special/.357 mangum.
Of this design, Tamara Keel writes:
When I was younger, I used to think cut-down lever guns, a la Steve McQueen's "Mare's Leg" were just the coolest thing ever.
Now that I am older and actually know a little bit about firearms, I think they make about as much sense as a kickstand on a tank.
They still look cool though, and, y'know... Firefly.
It probably wouldn't hurt their sales for Rossi to come out with a Firefly special edition.
