Well there was gun control as in places you couldn't carry, or you couldn't carry concealed, but I don't know of groups of people being excluded from owning a gun. I'm not a historical scholar either, so maybe.That is only one small reason for the gun control.
There were many places out west that began Gun Control long before there was gun control for the blacks.
There was gun control back east against all people before there was gun control against the blacks.

It's funny when you think of it that way. They used to not want people to conceal their firearms. If you were going to carry you were to carry openly so everyone knew it. Concealed carry was more "dangerous".
