Anybody here know if the Desantis Doc Holliday holster will fit the new Ruger Flattop Blackhawk revolver? I would like to carry my new Flattop 357 in the field in a cross draw holster and the Doc Holliday holster seems to like a good holster for the job... if it will fit the revolver. I was told that new Vaquero will fit but nobody seems to know if the flattop Blackhawk will fit. Hate to spend $50 on a holster and then find out it won't fit.
