Don, I am in the OKC area and I have extensive experience in weapon retention training / instruction in law enforcement, military, and civilian sectors. I have not conducted any such training since I have been in OK because I have been too busy with the job I moved down here for (EMSA). I have since suffered a career-ending injury and am now permanently disabled. I will soon be moving back to MI where I will resume my instruction in such disciplines as my full-time career. I tell you all this because I would be willing to conduct such training if you have a suitable environment in which to do so. I have another gentleman from the Norman area who I am currently trying to coordinate some basic pistol training for. If you happen to have access to a suitable location and you would be willing to participate in a class with another individual, please let me know in a private message and we can work something out. If you would prefer one-on-one training, then feel free to message me regarding that as well. When you message me, please let me know the extent of your current experience with firearms as well as the level of retention training you are seeking. Hopefully we can work something out within the next couple of months so that you don't have to spend a fortune to accomplish what you are trying to do.
