We've all seen him shooting in "I Spy" and "The Greatest American Hero," of course, but I found, talking about TV westerns:
"I really enjoyed Rick Hacker's article, "The Guns That Won the TV West" (February 2002, p. 60). It brought back pangs of nostalgia. I remember seeing every show mentioned, but you missed one goodie. Robert Culp played a lawman of some sort in Texas, and actually carried and seemed to know how to use his Smith & Wesson Schofield!" Here's the addy of where I found it: http://www.findarticles.com/p/articles/mi_qa3623/is_200204/ai_n9083999
Of course, the writer is talking about Robert in "Trackdown," in which he played a Texas Ranger (eat your heart out, Walker!) I don't recall his character's name, not ever seeing the show. If I remember right, Robert would've been only about 27 years old when he did this.
Bill even wears his gun when he's home in his scivvies. Talk about hard-core!
(I'll put in one of his "Trackdown" character when I get one.)
