Rangemaster will be doing a one day Defensive Shotgun Course at the Shawnee police range on Wed, Sept 23. That is an optional class after our Combative Pistol Course there on Sept 21-22. You can take the shotgun class by itself, if you wish. I'm not in my office right now, but I believe the fee is $185 for a full day of shotgun training.
I know this might be a little further out than what you want but we are putting on a 2 day Advanced Combat Shotgun Class in Sept. This class has always filled up in the past and is excellent for all applications with a shotgun. You think you know how to run one now???? Wait till you see what we do in this class. You'll be amazed. Just a thought.
