Actually I have "the other guy's" leather holster and belt for one of my other revolvers. I use the belt for my work belt, and when it gets wet with sweat the dye leaches out into my work clothes. I don't mind it with just the belt but a leather holster doing that all over me, my shorts and my pants and stuff... thanks for the idea but I see that problem coming.
That's one of the reason I'm leery of leather holsters for this application. Gotta be able to let literally gallons and gallons of sweat run off and not mess up my skin or my light-colored work clothes.
