First off,.sorry for my horrible typing last night.
Chuck Norris did carry a 6" 629 in both Lone Wolf McQuaide and the earlier seasons of walker. I heard, not verifyied, that t was the same revolver both tikes and one he owned personally. He is a big gun collector and competative shooter for those who didnt know.
For anyone who remembers the "88 Magnum" from Johnny Dangourusly, I owe you a beer once, ONCE
