Right now this is just a warm idea swirling around. Nothing is fixed, Back in my Doc Holilday period, I typically wore a 5 1/2 strong side but reverse draw (butt forward) and either a matching gun in a offside reverse draw OR a Sheriffs Model in a crossdraw worn closer to the center
Sometimes a 5 1/2 strong side and a Sheriffs in a period shoulder holster
If I was really feeling sporty in might be an Avenging Angle 1860 with a conversion cylinder
I even tried a custom Sheriffs (see the mystery pistol above) in a SOB holster

Remember your holster colour must match you belt and your belt should coordinate with your shoes. Please NO miss/match black/browns People notice....
