Open carry in Oklahoma

There were two interesting pieces of news here: 1) Open carry has passed in Oklahoma and 2) there are now about 125,000 permit holders in the state.  This open carry law is relatively restrictive in that it requires a concealed carry permit.  From CNBC:

A bill to allow Oklahomans with a concealed-carry permit to openly carry their handguns is headed to the governor, who is expected to sign the legislation that passed the state Senate on Thursday.
The bill, approved by a 33-10 vote, would allow those with a concealed-carry handgun permit to openly carry their firearms in holsters from November 1. Those without such permits could obtain a gun permit and openly carry a firearm if they meet legal criteria, pass a background check and undergo firearms training. . . .
 about 125,000 people in the state.
Oklahoma has been one of six states in the country to prohibit the open-carry of firearms, along with Texas, Florida, Illinois, New York and California (handguns only), according to the Brady Campaign, the gun control advocacy group in Washington, D.C. . . .
Some 44 states allow some form of open-carry firearms, with only 11 requiring permits to do so, according to the Brady Campaign. . . .
