Yes, No Second Place Winner. I think, but it's been a while, that while he never directly said what he carried, he implied that a 1911 is what he had. I could be wrong.
I haven't come across that article. My impression was that, while he preferred revolvers, he would have used what was issued to him and I don't remember any commentary about revolver reliability in military service.
Anyway, what Bill Jordan chose is not directly relevant to what is available today, and while I like revolvers, if I were to use a sidearm in the conditions an infantry guy would encounter, a gun that can run in spite of being very dirty and has a very low number of parts that I can replace myself without any smithing would get my vote. As it stands, a Glock does that and no revolver that I know of can. It doesn't mean a revolver can't be a good carry gun for every day life, it's just a different set of standards.
