I haven't seen this posted here yet. The Governor signed HB 1428 into law this week. http://webserver1.lsb.state.ok.us/cf_pdf/2017-18 ENR/hB/HB1428 ENR.PDF if I read this correctly it makes using shot shells out of the Judge/Governor type handguns legal as well as rat shot. It also appears to make AR pistols legal to carry. Now the practicality of these item is another story but they will be legal at least.
