"It really makes me wonder why HG carried a S&W.
Well, he had an IQ of 135, he must have a reason for that." - suum cuique

I will venture a guess: Goering had a flair for the dramatic, which included designing his own unique uniforms. His choice of a revolver only added to the impression that he was something special. And this kind of attitude is not unknown among flag rank officers. In America, Patton had his own pearl handled revolvers that he carried. And MacArthur chose to be frequently seen with a long stemmed cob pipe which was specially made for him in a small plant in Missouri. So it was probably not so much that the revolver was more dependable as it was a way to create the impression that Goering chose to make.
