The Rifleman's weapon was "in actuality" an 1892 .44-40 Winchester carbine specially modified with a large loop and metal tab to turn his rifle into a rapid firing machine.
It was fitted with a large loop lever that enabled it to be spun and cocked in a dramatic fashion. The trigger guard incorporated a screw that tripped the trigger every time the lever was closed.
In the words of Chuck Connors "We decided to take the rifle; take off the regular lever and put this round lever on so I could get my hand through it."

well, in the movies anyway. I'm not sure product liability was such a big deal in the 1800s.

Love the enlarged loop, dont know how useful it would be in practice since I never used one but it looks cool.
My favorite is John Waynes Hando.
