Most interesting comment, I found a rich frontier past opposed to open carry. You need to study Frontier justice and going armed. The first rules in Frontier towns was no carrying of firearms in town limits. They also banned the bearing of Bowie knives and swords.
Towns also banned sidearms being loaded on horseback while riding thru the streets. Reason, very often guns discharged killing and wounding horses which had to be removed from the streets. This was a cost to the City.
In most Frontier towns guns carried open in the range were carried concealed in town. When the famous gunman Tom Horn was arrested in Cheyenne he was carrying a Colt Army under his coat. After all it was the Cowboy Way.
